At medium and low operating temperatures, the slow reaction kinetics of cathode is a significant limiting factor hindering proton ceramic fuel cell (PCFC) development. This work reports Nd2–xSrxNi0.9Cu0.1O4+δ (x = 0, 0.2, 0.4, 0.6, 0.8, 1) Ruddlesden–Popper through combination strategy A-site Sr2+ B-site Cu2+ codoping. Appropriate doping has achieved synergistic optimization conductivity electrocatalytic activity by modulating amount surface oxygen defects valence state Ni2+....
Fabrication of Z-scheme heterojunction photocatalysts is an ideal strategy for solving environmental problems by providing inexhaustible solar energy. A direct anatase TiO2/rutile TiO2 photocatalyst was prepared using a facile B-doping strategy. The band structure and oxygen-vacancy content can be successfully tailored controlling the amount B-dopant. photocatalytic performance enhanced via transfer path formed between B doped anatase-TiO2 rutile-TiO2, optimized with markedly positively...
CdS has a wide visible-light response range and suitable energy band structure; it been spotlighted in the field of photocatalysis. Nevertheless, its poor photogenerated carriers separation efficiency leads to dissatisfying photocatalytic H2 production activity. In this work, we prepared hexagonal pyramid CdS-Ni(OH)2 hybrid photocatalyst. The maximal rate photocatalyst was 29.51 mmol/h/g, which 5.6 times 1.9 higher than CdS-Pt. A type II heterojunction can be formed between Ni(OH)2. improved...
Plasmonic effect-enhanced Z-type heterojunction photocatalysts comprise a promising solution to the two fundamental problems of current TiO2-based photocatalysis concerning low-charge carrier separation efficiency and low utilization solar illumination. A plasmonic TiN@anatase-TiO2/rutile-TiO2 photocatalyst with strong interface N-O chemical bond was synthesized by hydrothermal oxidation TiN. The prepared shows desirable visible light absorption good visible-light-photocatalytic activity....
The development of highly active photocatalysts in visible light response for photocatalytic hydrogen production has become a hot spot. In this work, we report MoS2-modified CdS hexagonal pyramid composite photocatalyst. It shows maximum H2 evolution rate 18.75 mmol g–1 h–1, which is 3.4 times higher than that pure CdS, and the apparent quantum efficiency 22.75% at 420 nm. confirmed separation photogenerated carriers can be improved after loading MoS2. Furthermore, surface photovoltage...
Nickel cobaltite (NiCo2O4) is a promising sensing material for H2O2. However, the poor electronic conductivity and agglomeration of NiCo2O4 in aqueous medium easily lead to sensitivity selectivity, which are still two formidable challenges. Herein, poly (3, 4-ethylene dioxythiophene)-coated rod-like micro-nano structures/reduced graphene oxide (NiCo2O4 [email protected]/RGO) hybrid synthesized. The one-dimension hierarchical RMNs serve as catalyst, while RGO acting support charge collector....
In order to address the anti-ablation of carbon/carbon (C/C) composites, SiC nanowires (SiCnws) network-modified C/C-ZrB2-ZrC-SiC composites were prepared through one-step precursor conversion method. With an optimized B-Si-Zr sol-precursor, uniformly dispersed SiCnws and ceramic particles forming interlocking structure synchronous in situ grown C/C matrix. During ablation, partially oxidized networks with molten SiO2 surface can stabilize oxide protecting layer heal microcracks efficiently...
