2020年10月5日 · Amorphous NiWO 4 nanoparticles are hydrothermally coupled on the surface of Ni 3 S 2. The materials exhibit improved HER activity than Ni 3 S 2 with ultra-long stability. Strong electronic interaction is found between NiWO 4 and Ni 3 S 2. The local electron density of Ni and S atoms is decreased at the interfaces.

2023年2月1日 · Remarkably, an electrolytic cell assembled by using NiWO 4 -Ni 3 S 2 @NiO/NF-3 as both anode and cathode delivered an overall-water-splitting current density of 10 mA cm −2 at 1.64 V, evidencing its robust bifunctional catalytic ability in water splitting. 1. Introduction.

Nuwa was Fuxi's sister, an assistant to Dr. Mobius, and a pioneer for Project EMBER, a goddess of the Shenzhou legends.

这种高折射率面曝光和电子密度优化的结合赋予了所得的 NiWO 4 -Ni 3 S 2 @NiO/NF-3（3 表示制造 Ni 3 S 2时标称的 Ni:S 摩尔比）电极更合适的H在Ni活性位点的吸附能和Ni 3 S 2 d带中心的正移向费米能级发展，导致 Ni-H 相互作用增强。

2024年1月30日 · 该研究通过构建NiS 2 /NiWO 4 /ZnIn 2 S 4 中空微球光催化剂，加速光产生电子的转移并促进更多氢离子从活性吸附水中释放，从而提高了光催化制氢效率。 研究人员发现，NiS 2 共催化剂中S-H ads 键合强度较大，阻碍了氢原子从活性S位点脱附，从而影响了NiS 2 的光催化制氢性能。 因此，研究人员通过将无定形的NiWO 4 纳米颗粒与NiS 2 共催化剂紧密接触，可以增强载流子的电荷分离，并作为“电子桥”加速电荷载流子的转移。 此外，无定形的NiWO 4 …
