“…Broadly speaking, the interface region formed by two different semiconductor contacts is called the heterojunction. Influenced by the position of the band structure, photogenerated electrons and holes can move between the two semiconductors through the heterojunction, that is, the heterojunction provides a new path for the transport of photocarriers. − The means of improving the separation efficiency of photogenerated carriers by recombining semiconductors with two different band structures has been widely proposed and studied. − …”

With a high porosity and highly adaptable topology, ZIF-67 is considered the most promising photocatalyst and has received much attention and development. However, the photoactive electron extraction rate of ZIF-67 is still low, which is a major problem limiting its further development. In this paper, based on the type I structure and using quantum dots (QDs) as the active site, we obtain the QDs@ZIF-67/ZIF-8 heterostructure, which ensures high-yield hydrogen efficiency. Quantum dots, as the transmission site of photogenerated electrons, improve the photogenerated carrier utilization rate generated by the strong absorption ability of ZIF-67 in the visible-light region. Through careful characterization, it was found that the optimal photocatalytic rate of 4999.7 μmol•g −1 •h −1 , a value 30 times higher than that of QDs, provides an innovative band gap-matching design for adjusting the charge transfer characteristics of QDs with a narrow band gap, which realizes the efficient utilization of visible light.

“…In contrast, constructing hierarchical hollow structures with a shell assembled from 2D sheets can increase the active area and enhance the accessibility of the interior, leading to an excellent matter transport. 16,17 Inspired by the above advantages, hollow heterostructural materials are supposed as promising catalysts in the PHER. Nevertheless, neither the construction of heterostructures nor the synthesis of hollow structures has simple processes.…”

“…[12] Regrettably, more than 95% of hydrogen is produced from thermocatalytic steam reforming of fossil resources (e.g., natural gas, coal, and petroleum) under high temperatures and high pressure with the virtual limitations of huge thermal input, fierce carbon footprint, and concomitant environmental issues (Figure 1a), which is known as gray hydrogen. [13,14] Specifically, during the process of gray hydrogen production, ≈830 million tons of carbon dioxide are generated annually, accounting for more than 2% of global carbon dioxide emissions. [15,16] It is not sustainable and cannot meet the massive demand for green hydrogen by a carbon-neutral economy system in the future.…”

Hydrogen (H2) has emerged as a clean and versatile energy carrier to power a carbon‐neutral economy for the post‐fossil era. Hydrogen generation from low‐cost and renewable biomass by virtually inexhaustible solar energy presents an innovative strategy to process organic solid waste, combat the energy crisis, and achieve carbon neutrality. Herein, the progress and breakthroughs in solar‐powered H2 production from biomass are reviewed. The basic principles of solar‐driven H2 generation from biomass are first introduced for a better understanding of the reaction mechanism. Next, the merits and shortcomings of various semiconductors and cocatalysts are summarized, and the strategies for addressing the related issues are also elaborated. Then, various bio‐based feedstocks for solar‐driven H2 production are reviewed with an emphasis on the effect of photocatalysts and catalytic systems on performance. Of note, the concurrent generation of value‐added chemicals from biomass reforming is emphasized as well. Meanwhile, the emerging photo‐thermal coupling strategy that shows a grand prospect for maximally utilizing the entire solar energy spectrum is also discussed. Further, the direct utilization of hydrogen from biomass as a green reductant for producing value‐added chemicals via organic reactions is also highlighted. Finally, the challenges and perspectives of photoreforming biomass toward hydrogen are envisioned.
