Following the photodeposition of CoOx, Pd as an oxygen-reduction reaction (ORR) cocatalyst was selectively deposited on the {010} facet of Mo:BiVO4via photoreduction of PdCl42−(Fig.1a). The loading amount of Pd was optimized to be 0.4 wt% based on the activity of photocatalytic H2O2...
of half reactions,ie.,the oxygen reduction reaction(ORR)and water oxidation reaction(WOR),greatly restricts the efficiency of photocatalytic H2O2 production.In this highlight,we discuss the significant ad-vances in molecular engineering of carbon nitrides for H2O2 photosynthesis and the importanc...
Metal–organic frameworks (MOFs) have been studied extensively in the hydrogen evolution reaction (HER) and the water oxidation reaction (WOR) with sacrificial reagents, but overall photocatalytic water splitting using MOFs has remained challenging, principally because of the fast recombination of photo-...
Fig. 3a shows an SEM image of the phosphorus nanosheets. It can be seen that, following the hydrothermal reaction, the red phosphorus microspheres formed a relatively uniform nano-flake structure. A high-resolution SEM image of the phosphorus nanosheets is shown in Fig. 3b; the phosphorus sheets...
Photocatalytic overall water splitting can be achieved using Z-scheme systems that mimic natural photosynthesis by combining dissimilar semiconductors in series. However, coupling well-suited H- and O-evolving components remains challenging. Here, we fabricate a Z-scheme system for photocatalytic overall ...

It is highly desirable to simulate natural photosynthesis by using sunlight to drive the overall water splitting without using external bias and sacrificial agent. Herein, few-layer monoclinic BiVO4 nanosheets (BVNS) with a thickness of (∼)4.3 nm, exposed (010) facets and abundant oxygen vacanc...
Abstract Converting solar energy into hydrogen (H2) by photocatalytic water splitting is a promising approach to simultaneously address the increasing energy demand and environmental issues. Half decade has passed since the discovery of photo-induced water splitting phenomenon on TiO2photoanode, while the...
