“…Therefore, the vigorous development of renewable energy is not only conducive for sustainable economic development but also for alleviating the increasingly serious energy and environmental problems. As a potential renewable energy source, solar energy, especially visible light (which accounts for most of the solar energy), is believed to contribute to mitigating these problems through photocatalytic technology (also known as semiconductor-based photocatalytic technology) [1]. Semiconductor-based photocatalysis has attracted considerable attention due to its direct conversion of solar energy to easily stored hydrogen, as well as free secondary pollution [2,3].…”

The electronic structures and optical characteristics of yttrium (Y)-doped ZnO monolayers (MLs) with vacancy (zinc vacancy, oxygen vacancy) were investigated by the first-principles density functional theory. Calculations were performed with the GGA+U (generalized gradient approximation plus U) approach, which can accurately estimate the energy of strong correlation semiconductors. The results show that the formation energy values of Y-doped ZnO MLs with zinc or oxygen vacancy (VZn, VO) are positive, implying that the systems are unstable. The bandgap of Y-VZn-ZnO was 3.23 eV, whereas that of Y-VO-ZnO was 2.24 eV, which are smaller than the bandgaps of pure ZnO ML and Y-doped ZnO MLs with or without VO. Impurity levels appeared in the forbidden band of ZnO MLs with Y and vacancy. Furthermore, Y-VZn-ZnO will result in a red-shift of the absorption edge. Compared with the pure ZnO ML, ZnO MLs with one defect (Y, VZn or VO), and Y-VZn-ZnO, the absorption coefficient of Y-VO-ZnO was significantly enhanced in the visible light region. These findings demonstrate that Y-VO-ZnO would have great application potential in photocatalysis.

“…As mentioned earlier, the first step of CO 2 activation is very difficult. One general mechanism of pCO 2 RR involves one‐electron activation of CO 2 to CO 2 − intermediate (−1.9 V vs. Normal Hydrogen Electrode (NHE)) [7d] . As a result, bending linear CO 2 molecule into highly active radical anion CO 2 − needs immense overpotential.…”

After postdoctoral research at the University of Tokyo and the University of California at Berkeley, at the end of 2003, he joined the faculty of Peking University. His research focuses on fundamental studies of catalyst structures and reaction mechanisms, towards the design of heterogeneous catalysts and control of reaction pathways for selective conversion of biomass and its derivatives into chemicals, as well as other reactions important in renewable energy conversion and utilization.

“…However, CO 2 reduction suffers greatly from poor selectivity as plethora of products are produced at small quantities, and limit adsorption of CO 2 gas on photocatalysts’ surface . Up to now, no more complex structures than two‐carbon (C2) molecules can be efficiently produced with high selectivity by a photocatalytic route . Unless a major breakthrough in high precision catalyst is achieved, the profitability of CO 2 reduction will be determined by the cost of separation and the industrial application of artificial photosynthesis for CO 2 reduction could be far‐fetched…”

Beyond Artificial Photosynthesis: Prospects on Photobiorefinery

Artificial photosynthesis (AP) technology which integrates solar energy harvesting and chemical conversion process into one device is a promising solution to both global energy and environmental crises. Despite decades of research, AP for solar hydrogen production and CO2 reduction remains in the technological infancy. The low profit margins of the targeted products, the highly energy‐intensive process, and the engineering impracticality have kept AP technology in the laboratory demonstration stage. Photobiorefinery, a photocatalytic process for biomass valorization, has emerged as a new promising application for AP technology. This process offers high‐value products, requires less energy, and potentially could utilize AP process to enhance selectivity. In this Minireview, the recent progress in photocatalytic biomass depolymerization, partial oxidation, hydrogenolysis, and hydrogenation are featured. Challenges and prospects of the photocatalytic biomass valorization towards commercialization are also discussed.
