Energy from renewable resources is central to environmental sustainability. Among the renewables, sunlight-driven fuel synthesis is a sustainable and economical approach to produce vectors such as hydrogen through water splitting. The photocatalytic water splitting is limited by the water oxidation half-reaction, which is kinetically and energetically demanding and entails designer photocatalysts. Such challenges can be addressed by employing alternative oxidation half-reactions. Photoreforming can drive the breakdown of waste plastics and biomass into valuable organic products for the production of H2. We provide an overview of photoreforming and its underlying mechanisms that convert waste polymers into H2 fuels and fine chemicals. This is of paramount importance from two complementary perspectives: (i) green energy harvesting and (ii) environmental sustainability by decomposing waste polymers into valuables. Competitive results for the generation of H2 fuel without environmental hazards through photoreforming are being generated. The photoreforming process, mechanisms, and critical assessment of the field are scarce. We address such points by focusing on (i) the concept of photoreforming and up-to-date knowledge with key milestones achieved, (ii) uncovering the concepts and challenges in photoreforming, and (iii) the design of photocatalysts with underlying mechanisms and pathways through the use of different polymer wastes as substrates.

用于可持续氢燃料和化学品原料的废聚合物的光转化:废物转化为能源

来自可再生资源的能源是环境可持续性的核心。在可再生能源中,阳光驱动的燃料合成是一种可持续且经济的方法,可以通过分解水来生产氢等载体。光催化水分解受到水氧化半反应的限制,这对动力学和能量要求很高,需要设计光催化剂。这些挑战可以通过采用替代氧化半反应来解决。光重整可以将废塑料和生物质分解成有价值的有机产品,用于生产 H 2。我们概述了光重整及其将废聚合物转化为 H 2的潜在机制燃料和精细化学品。从两个互补的角度来看,这是至关重要的:(i)绿色能源收集和(ii)通过将废聚合物分解成有价值的东西来实现环境可持续性。通过光重整产生无环境危害的 H 2燃料的竞争性结果正在产生。该领域的光重整过程、机制和批判性评估很少。我们通过关注 (i) 光重整的概念和最新知识以及实现的关键里程碑来解决这些问题,(ii) 揭示光重整中的概念和挑战,以及 (iii) 具有潜在机制和途径的光催化剂设计通过使用不同的聚合物废料作为基材。
