此外,与Re50-NiCr LDH的Cr 2p峰相比,Re50-S0.02-NiCr LDH中嘈杂的Cr 2p光谱归因于电化学活化过程中的Cr浸出,这可能是硫掺杂后形成的Cr-S键的强度低于Cr-O键的强度,从而加快了Cr的浸出速度。ReC-NiCr LDH(C=50和100)和ReC-S0.02-NiCr LDH(C=50和100)的Ni 2p光谱显示Ni3+的峰面积显著增加。此外,ReC-...
In this study, modified NiCr-LDH using Spirogyra sp. algae (SA), a filamentous green macro-algae was applied to remove remazol red (RR), an anionic dye from an aqueous solution. NiCr-LDH with SA (NiCr-SA) composite materials were synthesized using the coprecipitation-hydrothermal method and...
本发明属于光催化技术领域,具体涉及一种Z型CdIn2S4/NiCr‑LDH异质结光催化剂及其制备方法和应用,所述CdIn2S4/NiCr‑LDH异质结光催化材料是在NiCr‑LDH二维层状纳米片上负载CdIn2S4,并通过在界面形成Ni‑S键紧密结合。本发明的CdIn2S4/NiCr‑LDH光催化剂中CdIn2S4导带和价带电位高于NiCr‑LDH能够促进异质...
The photocatalytic H2evolution rate of CdIn2S4/In(OH)3/NiCr-LDH increased to 10.9 and 58.7 times that of the counterparts CdIn2S4and NiCr-LDH, respectively. Moreover, the photocatalytic removal efficiency of Cr(VI) increased from 6% for NiCr-LDH and 75% for CdIn2S4to 97% for CdIn2S4/...
华中科技大学ACS Catalysis:应变工程立大功,调节Ru-NiCr LDH d带中心来促进碱性HER 氢能因其超高的能量密度和环保特性而受到广泛关注,而钌(Ru)被认为是催化碱性析氢反应(HER)的有前途的候选催化剂,但其需要优化对氢的吸附以提高电催化活性。现今应变工程已被证明是调节关键反应中间体结合强度和增强催化活性的...
2、通过XPS、原位Raman表征和DFT计算,揭示了NiCr LDH重构为活性NiOOH,而且硫掺杂降低了NiCr LDH的重构能垒和促进晶格氧氧化。 3、将重构的催化剂在25°C和80°C下进行水分解,在10 mA cm-2下分别需要1.51和1.47 V的电压。 图文解析...
