Abstract
Biomass is a renewable hydrogen and carbon source, and it is of interest to use as a sustainable resource. Solar-driven photocatalysis has been recognized as a potentially feasible technology for the extraction of hydrogen from biomass to produce molecular hydrogen. Traditionally the carbon content in biomass has been degraded to carbon dioxide, but increasing efforts aim to produce value-added carbon chemicals instead. This perspective summarizes existing strategies for the photocatalytic coproduction of hydrogen and renewable carbon-based chemicals (H2 + Cx) and analyzes reforming routes to H2 + CO, controlled oxidation to aldehydes, and dehydrocoupling to form dimer complexes. Hydrogen is a clean burning fuel, and the as-formed Cx compounds can be used as value-added fine chemicals, fuels, or precursors. Future visions on scientific, technological, and economic issues for biomass-derived hydrogen and carbon-compound evolution are put forward to determine research focus areas in the coming decades.
期刊介绍：
Joule is a sister journal to Cell that focuses on research, analysis, and ideas related to sustainable energy. It aims to address the global challenge of the need for more sustainable energy solutions. Joule is a forward-looking journal that bridges disciplines and scales of energy research. It connects researchers and analysts working on scientific, technical, economic, policy, and social challenges related to sustainable energy. The journal covers a wide range of energy research, from fundamental laboratory studies on energy conversion and storage to global-level analysis. Joule aims to highlight and amplify the implications, challenges, and opportunities of novel energy research for different groups in the field.
