Rational construction of dual cocatalysts corresponding to different facets with photogenerated charge separation.
Highly efficient water oxidation utilizing visible photons of up to 600 nm is a crucial step in artifical photosynthesis. Here we present highly active photocatalyst for visible-light-driven oxidation, consisting single-crystalline meso- and macroporous LaTiO2N (LTON) with band gap 2.1 eV, earth-abundasnt cobalt oxide (CoOx) as cocatalyst. The optimized CoOx/LTON had high quantum efficiency 27.1 ± 2.6% at 440 nm, which substantially exceeds the values reported previous particulate...
Photoelectrochemical (PEC) water splitting is an ideal approach for renewable solar fuel production. One of the major problems that narrow bandgap semiconductors, such as tantalum nitride, though possessing desirable band alignment splitting, suffer from poor photostability oxidation. For first time it shown presence a ferrihydrite layer permits sustainable oxidation at nitride photoanode least 6 h with benchmark photocurrent over 5 mA cm(-2) , whereas bare rapidly degrades within minutes....
Bismuth vanadate (BiVO4) has been widely investigated as a photocatalyst or photoanode for solar water splitting, but its activity is hindered by inefficient cocatalysts and limited understanding of the underlying mechanism. Here we demonstrate significantly enhanced oxidation on particulate BiVO4 via in situ facet-selective photodeposition dual-cocatalysts that exist separately metallic Ir nanoparticles nanocomposite FeOOH CoOOH (denoted FeCoOx), revealed advanced techniques. The mechanism...
Abstract Cocatalysts have been extensively used to promote water oxidation efficiency in solar‐to‐chemical energy conversion, but the influence of interface compatibility between semiconductor and cocatalyst has rarely addressed. Here we demonstrate a feasible strategy wettability modification enhance state‐of‐the‐art CoO x /Ta 3 N 5 system. When hydrophobic feature Ta was modulated hydrophilic one by situ or ex surface coating with magnesia nanolayer (2–5 nm), interfacial contact modified...
An (oxy)nitride-based heterostructure for powdered Z-scheme overall water splitting is presented. Compared with the single MgTa2O(6-x)N(y) or TaON photocatalyst, a MgTa2O(6-x)N(y)/TaON fabricated by simple one-pot nitridation route was demonstrated to effectively suppress recombination of carriers efficient spatial charge separation and decreased defect density. By employing Pt-loaded as H2-evolving system an apparent quantum efficiency (AQE) 6.8% at 420 nm constructed (PtO(x)-WO3...
The development of new metal-organic frameworks (MOFs) with dual functions both water reduction and oxidation under visible-light irradiation is highly desirable for promising solar splitting, but not yet reported. Herein, a cadmium-based MOF (denoted as "Cd-TBAPy") single crystal 2D layered framework by employing 1,3,6,8-tetrakis(p-benzoic acid)pyrene (H4 TBAPy) an organic linker reported, which exhibits good absorption edge ≈600 nm.

Development of water-stable metal-organic frameworks (MOFs) for promising visible-light-driven photocatalytic water splitting is highly desirable but still challenging. Here we report a novel p-type nickel-based MOF single crystal (Ni-TBAPy-SC) and its exfoliated nanobelts (Ni-TBAPy-NB) that can bear wide range pH environment in aqueous solution. Both experimental theoretical results indicate feasible electron transfer from the H4TBAPy ligand (light-harvesting center) to Ni-O cluster node...
Abstract Single-atom catalysts supported on solid substrates have inspired extensive interest, but the rational design of high-efficiency single-atom is still plagued by ambiguous structure determination active sites and its local support effect. Here, we report hybrid an axial coordination linkage molecular cobalt phthalocyanine with carbon nanotubes for selective oxygen reduction reaction screening from a series metal phthalocyanines via preferential density-functional theory calculations....

Herein we report a single-atomic Bi decorated Cu (denoted as BiCu-SAA) electrocatalyst that could effectively modulate selectivity CO2 C2+ instead previous C1 ones. The BiCu-SAA catalyst exhibits remarkably superior with optimal Faradaic...
Iron (Fe)-based bimetallic oxides/hydroxides have been widely investigated for promising alkaline electrochemical oxygen evolution reactions (OERs), but it still remains argumentative whether Fe3+ or Fe4+ intermediates are highly active efficient OER. Here, we rationally designed and prepared one Fe, V-based composite nanosheet by employing the OER-inert V element as a promoter to completely avoid argument of real metals using our recently developed one-dimensional conductive nickel...

We report a spontaneous phase transformation of titania nanotubes induced by water at room temperature, which enables the as-anodized amorphous to be crystallized into anatase mesoporous nanowires without any other post-treatments. These TiO(2) nanomaterials have markedly improved surface area, about 5.5 times than that nanotubes, resulting in pronounced enhanced photocatalytic activity. The present approach not only allows flexible control over morphology nanostructures but can...
Hematite is a promising photoanode material for renewable solar fuel production via photoelectrochemical (PEC) water splitting. However, the fast electron–hole recombination and sluggish surface reaction retard it from getting satisfied performance. Herein, hematite nanorod arrays doped with titanium (Ti–Fe2O3) on were prepared by solution-based process. Because of one-dimension anisotropy improved charge transfer property, photocurrent density doubled compared to pure Fe2O3 at 1.50 V vs RHE...
