Recently in Chem Catalysis, He and co-workers proposed the efficient conversion of methane to methanol under moderate conditions via the active O species in situ generated from photo-splitting of H2O over Co-SrTiO3 tandem catalysts. Using characterization techniques, the authors determined the intermediates and mechanism of the reaction.

The mechanism of MOF crystal growth is fundamentally important to their design. In this issue of Chem, Deng and co-workers use an optical method to visualize and track the crystal interface during MOF growth. They derive a reaction kinetic equation for individual crystals of MOFs, thereby offering guidance to MOF synthesis.

Water splitting is an important technology for green hydrogen production. However, the sluggish kinetics of the anodic oxygen evolution reaction limit device performance. Furthermore, under acidic conditions, sparse and expensive iridium-based catalysts are required. In the May issue of Chem, Lu et al. explored mild electrochemical oxidation treatments to transform graphite flakes into promising oxygen

Recently in Science, Hutchings and co-workers reported an efficient TS-1-supported AuPd alloy nanoparticle catalyst that produced cyclohexanone oxime with a selectivity > 95% through the in-situ-generated H2O2, comparable to the current industrial route. The use of in-situ-generated H2O2 can achieve great cost savings in current industrial production of oxime and is believed to have bright prospects

In the May issue of Cell Reports Physical Science, Gale and co-workers document a lantern-like receptor (superphane) containing a tailor-made cavity for selective binding of perrhenate anion, leading to an extraordinary capability to separate perrhenate from complex aqueous solutions by either liquid-liquid extraction or solid-phase extraction.

The presence of residues in products generated by high-efficiency catalytic reactions is detrimental. In a recent work published in Nature Nanotechnology by Andrea Schäfer and colleagues, membrane catalysts are shown to promote processes while enhancing water purification by degradation of micropollutants via filtration-driven effective collision.

Conversion of CO2 into specific light olefins with high selectivity is a challenge. In this issue of Chem, Fan and co-workers propose an ethanol-intermediate route with the design of a new catalyst: Cr2O3(SG)/H-SAPO-34. The C2=–C4= selectivity can reach 95.7%, and ethene accounts for 74% of light olefins in CO2 hydrogenation.

The thioredoxin system is a critical regulator of redox processes across eukaryotes, but precise monitoring of its activity is made difficult by the lack of selective cellularly active probes. In this issue of Chem, Thorn-Seshold and co-workers utilize a rational design approach to develop a highly selective selenylsulfide probe for monitoring thioredoxin reductase activity in live cells.

Molecular recognition is at the heart of the noncovalent synthesis of supramolecular assemblies and, at higher length scales, supramolecular materials. In a recent publication in Nature, Stoddart and co-workers demonstrate that the formation of host-guest complexes can be catalyzed by one of the simplest possible catalysts: the electron.

In a recent issue of Nature Communications, Ozin, Wang, and co-workers report a new black indium oxide for photothermal tandem CO2 hydrogenation to methanol via CO2 hydrogenation to CO and CO hydrogenation. The tandem methanol synthesis strategy illustrates an important step toward catalytic synthesis of solar methanol.

Precipitation behavior is crucial to utilizing sulfur cathodes in lithium-sulfur (Li-S) batteries. In this issue of Chem, Rennie and co-workers apply operando scattering techniques to reveal correlations between precipitation reactions and the electrochemical performance of sulfur cathodes and demonstrate that Li+ supply in carbon mesopores is significant for precipitation reactions and thus sulfur

Microbial biomanufacturing relies heavily on sugar feedstocks, limiting efforts to transition toward carbon neutrality. In a recent issue of Nature Biotechnology, Liew and co-workers show that engineering autotrophic bacteria enables carbon-negative biomanufacturing of chemicals from waste gas feedstocks at an industrial pilot scale, which provides a roadmap for a circular carbon economy.
