Metal-semiconductor oxide (WO3@W) induces an efficient electro–photo synergistic catalysis for MOR and ORR

Electrostatic Interaction in Amino Protonated Chitosan–Metal Complex Anion Hydrogels: A Simple Approach to Porous Metal Carbides/N-Doped Carbon Aerogels for Energy Conversion

“…Based on the exploration of new sustainable energy systems, electrochemical energy conversion technology has been developed rapidly. Electrocatalysts play a key role in energy conversion technology because they improve the rate and efficiency of the chemical conversion involved. − However, commercial electrocatalysts are largely dependent on precious metals, such as Pt, Pd, Ru, Rh, and so forth. − For example, platinum (Pt)- and iridium (Ir)/ruthenium (Ru)-based catalysts are deemed to be the best catalysts for oxygen reduction reaction (ORR), but their high cost and scarcity limit the development and application of electrochemical energy conversion technology. − With the development of technology and the demand for high performance of electrocatalysts, the low-cost transition metal-based materials with efficient electrocatalystic activities are widely considerable. , …”

Tailoring charge reconfiguration in dodecahedral Co2P@carbon nanohybrids by triple-doping engineering for promoted reversible oxygen catalysis

“…79 With this in mind, to confirm the expected electronic-structure regulation of the catalysts, ultraviolet photoemission spectroscopy was performed to measure their electron-donating abilities. 80,81 As depicted in Fig. S20a–d,† the calculated working function ( φ ) of Fe-Co 2 P@NPDC is found to be 4.26 eV, smaller than those of Co 2 P@NPDC (4.79 eV), NPDC (6.62 eV) and NDC (6.70 eV).…”

Photocatalytic fuel cell – A review

“…Based on the location of O 2p orbital, the VB positions of binary metal oxides are more positive than that of oxidation positions, leading to wide energy bandgaps. [70] Strong solar PFC effect could also be obtained by making the photoanode with other visible-light absorption semiconductor materials, such as WO3/W, [71][72][73][74] ZnO/Zn, [75] Nb2O5 [72] and BiOCl. [76] However, the performance of PFC consisting of CdS/WO3 composite electrode exhibits poor stability due to photocorrosion, poor photoexcited charge separation and unfavorable band structure.…”
