Ag2O/Bi2O2CO3 p-n heterojunctions are prepared with commercial Bi2O2CO3 as precursor via a simple photosynthesis process. The obtained show higher photocatalytic activity than that of pure n-Bi2O2CO3, and the (AB-4) heterojunction exhibits best under visible light (λ > 400 nm), which Rhodamine B, methyl blue orange can be completely degraded within 12 min. Photoluminescent spectra photoelectrochemical measurement further indicate greatly enhance charge generation suppress recombination...
Water splitting is considered as a pollution-free and efficient solution to produce hydrogen energy. Low-cost electrocatalysts for the evolution reaction (HER) oxygen (OER) are needed. Recently, chemical vapor deposition used an effective approach gain high-quality MoS2 nanosheets (NSs), which possess excellent performance water comparable platinum. Herein, NSs grown vertically on FeNi substrates obtained with in situ growth of Fe5 Ni4 S8 (FNS) at interface during synthesis . The synthesized...
Layer double hydroxide (LDH) has been widely applied to electrocatalysis, especially toward the oxygen evolution reaction (OER), owing its flexible layered structure and multifunctionality. Herein, FeNi LDH nanosheet arrays are directly synthesized on various metal foils by a facile hydrothermal method. Compared with single Fe or Ni substrates, obtained LDH/FeNi foil exhibited an ultrasmall onset overpotential of ∼90 mV, high catalytic activity (overpotential 130 mV @ 10 mA/cm2), durable...
Type I photosensitization provides an effective solution to the problem of unsatisfactory photodynamic therapeutic (PDT) effects caused by tumor hypoxia. The challenge in development mode is boost photosensitizer's own electron transfer capacity. Herein, we found that use bovine serum albumin (BSA) encapsulate a thermally activated delayed fluorescence (TADF) photosensitizer PS can significantly promote PDT process generate mass superoxide anions (O2•–). This opened new strategy employing...
Icosahedral, octahedral, and cubic Pd@Pt core-shell nanocrystals with two atomic Pt layers are epitaxially generated under thermodynamic control. Such icosahedra exhibit remarkably enhanced catalytic properties for oxygen reduction reaction compared to the octahedra cubes as well commercial Pt/C, which can be attributed ligand geometry effects, especially twin-induced strain effect that is revealed by geometrical phase analysis.
Abstract Facile fabrication of advanced catalysts toward oxygen reduction reaction with improving activity and stability is significant for proton‐exchange membrane fuel cells. Based on a generic solid‐state reaction, this study reports modified hydrogen‐assisted, gas‐phase synthesis facile, scalable production surfactant‐free, thin, platinum‐based nanowire‐network electrocatalysts. The free‐standing platinum platinum–nickel alloy nanowires show improvements up to 5.1 times 10.9 mass minimum...
Abstract In most of the reported n–n heterojunction photocatalysts, both conduction and valence bands one semiconductor are more negative than those other semiconductor. this work, we designed synthesized a novel photocatalyst, namely CdS‐ZnWO 4 heterojunctions, in which ZnWO has band positive CdS. The hydrogen evolution rate CdS‐30 mol %‐ZnWO reaches 31.46 mmol h −1 g under visible light, is approximately 8 755 times higher that pure CdS similar conditions, respectively. location surface...
Single atom catalyst and ultrathin two-dimensional (2D) nanostructures exhibit improved properties because of the exposure more active atomic sites optimized electronic structures. However, oxygen reduction reaction (ORR) in fuel cells via a fast four-electron path usually uses at least two Pt atoms, which cannot be realized highly isolated single atoms. The synthesis densely dispersed with adjacent atoms accessible same time on matrix high surface area provides feasible way and, however, is...
