Essential organic molecules are frequently the result of many synthetic procedures. These synthetic methods often involve harmful and endangered metals, expensive ligands, and toxic organic solvents. (1,2) Such agents can adversely affect health, the environment, and natural resource reserves. Therefore, chemists are advancing catalysis by developing technologies that involve biocatalysts, earth-abundant

Separating n-butene and i-butene by adsorption is an energy-efficient alternative, but designing porous adsorbents that distinguish the subtle differences between the isomers is extremely challenging. Currently, adsorbents that can sieve 1-butene isomers and are stable enough to withstand humid gas mixtures are largely unmet. Herein, we propose a robust ultramicroporous metal–organic framework (MET-Fe)

The conversion of industrial exhaust gases of nitrogen oxides into high-value products is significantly meaningful for global environment and human health. And green synthesis of amino acids is vital for biomedical research and sustainable development of mankind. Herein, we demonstrate an innovative approach for converting nitric oxide (NO) to a series of α-amino acids (over 13 kinds) through electrosynthesis

We present the first total synthesis of the thiamyxins A-C and the now fully characterized thiamyxin E, an interesting class of thiazole- and thiazoline-rich depsipeptides with diverse antiviral activity. The synthesis features a parallel closing of two methyl thiazoline units, with low epimerization of the very labile adjacent stereocenter. It also includes the three-step synthesis of an uncommon

Solar-to-electrochemical energy storage in solar batteries is an important solar utilization technology comparable to solar-to-electricity (solar cells) and solar-to-fuel (photocatalytic cells) conversion. Unlike the indirect approach of integrated solar flow batteries combining photoelectrodes with redox-electrodes, coupled solar batteries enable direct solar energy storage, but are hampered by low

Covalent organic frameworks (COFs), possessing pre-designable structures and tailorable functionalities, are promising candidates for photocatalysis. Nevertheless, the most studied imine-linked COFs (Im-COFs) usually suffer from unsatisfactory stability and photocatalytic performance. To meet this challenge, a series of highly stable enaminone-linked COFs (En-COFs) have been synthesized and afford

Herein, we report the synthesis of anthracene containing twisted Cyclo[2]dipyrrin 1 utilizing a non-planar building block, 1,5-dipyrrylanthracene (1,5-DPA). The non-planar nature of macrocycle enhanced the solubility and helps in structural characterization. Macrocycle 1 adopts a twisted ‘figure of eight’ conformation stabilized by strong intramolecular H-bonding interactions and exist as a pair of

In photosynthesis, solar energy is harvested by photosensitizers, and then, the excited electrons transfer via a Z-scheme mode to enzymatic catalytic centers to trigger redox reactions. Herein, we constructed a core-shell Z-scheme heterojunction of semiconductor@single-atom catalysts (SACs). The oxygen-vacancy-rich ZnO core and single-atom Co-N4 sites supported on nitrogen-rich carbon shell (SA-Co-CN)

Photocatalytic CO2 reduction (PCR) expresses great attraction to convert useless greenhouse gas into valuable chemical feedstock. However, the weak interactions between catalytic sites and PCR intermediates constrains the PCR activity and selectivity. Herein, we proposed a new strategy to match the intermediates due to the maximum orbital overlap of catalytic sites and C1 intermediates by establishing

Cyclopropene hydrofunctionalization has been a promising strategy for accessing multi-substituted cyclopropanes; however, cyclopropene hydroalkylation remains underdeveloped. Herein, we report a low-valent CoH-catalyzed facial-selective cyclopropene hydroalkylation to access multi-substituted cyclopropanes. This reaction exhibits a broad substrate scope of alkyl halides and cyclopropenes and tolerates

From an environmental and resource management perspective, it is preferable to recover and reuse heavy metal ions found in electroplating wastewater. The discharge of electroplating wastewater has caused serious environmental pollution and resource waste. Ca-based layered double hydroxides (LDHs) stabilizers are designed, which show a rapid, effective, and adequate capacity exceeding 400 mg/g against

The selective flotation recovery of gold from secondary resources is a sustainable strategy to fill the ever-increasing demand for gold resources, and reduce the environmental pollution. In the present work, a novel method to realize the selective and fast recovery of Au(III) in the flotation process involving the use of thermo-responsive amphiphilic polymer poly(ethylene glycol)-b-poly(N-isopropy

Through thermodynamic calculations, the E-pH diagrams of the Bi-S-H2O and Bi-S-Cl-H2O systems at 298K were plotted, the dominant regions of the components in the system and their changes with pH were clarified, and the mechanism and thermodynamic conditions for the decomposition of Bi2S3 in acidic systems were clarified. The key to the decomposition of Bi2S3 in acidic systems was based on the coordination

Vacuum membrane distillation (VMD) is characterized by high permeate flux and low conductive heat loss among the membrane distillation technologies. However, the inescapable polarization effect severely deteriorates the distillation performance and service life. Thus, this study aimed at establishing a novel slug flow-enhanced VMD system to effectively address the polarization problem and investigating

Superhydrophobic materials have been extensively investigated for their ability to separate oil/water mixtures, but their fragile durability has limited further development in this field. In this study, a durable superhydrophobic wire-cotton-based material (SWCM) was prepared by weaving metal wire and cotton fiber and modifying it with a mixed poly(vinyl phenol) (PVPh)/1,3-phenylene bisoxazoline (PBO)

Environmental issues caused by food waste are important concerns for human well-being and ecosystem health. Valorization of food waste into energy and carbon materials has been extensively investigated. Here, we reviewed the most recent advancements in the thermochemical conversion of food waste into engineered biochar. Synthesis routes and practical applications of the food waste-derived biochar was

Droplet and bubble manipulation on functional surfaces is a critical issue in numerous applications such as microreactor, microfluidic, biological, and gas transport. Despite recent efforts in tuning the physicochemical properties of responsive surfaces to impart functionalities in response to different external stimuli, it remains challenges to manipulate both the droplet and the bubble simultaneously

Ammonia (NH3) is an essential chemical in agriculture and industry, which plays a crucial role in human life and sustainable development. To date, ammonia production mainly relies on the energy-intensive Haber-Bosch process, resulting in significant energy consumption and CO2 emissions. Electrocatalytic nitrogen reduction reaction (NRR) that can produce NH3 under ambient conditions is considered as

Soft actuators capable of reversible, strong and multiple actuations with minimum energy consumption are highly desired for the areas like soft robotics and internet of things. However, it remains highly challenging to achieve multiple-way actuations with materials having high mechanical strength and via a simple procedure. Here, accurate solvent sensing and solvent-induced actuations are realized
