Organic–inorganic halide perovskite solar cells (PSCs) have achieved great success in
recent years with a demonstrated power conversion efficiency (PCE) increasing rapidly from …

Electrochromic (EC) materials are able to change their optical properties, reversibly and
persistently, by the application of an electrical voltage. These materials can be integrated in …

Oxygen vacancies (OVs) play a crucial role in the catalytic activity of metal-based catalysts;
however, their activation mechanism toward peroxydisulfate (PDS) still lacks reasonable …

Excitonic effects mediated by Coulomb interactions between photogenerated electrons and
holes play crucial roles in photoinduced processes of semiconductors. In terms of …

The performance enhancement of inverted perovskite solar cells applying nickel oxide
(NiOx) as the hole transport layer (HTL) has been limited by impurity ions (such as nitrate …

Herein, we report the one-pot co-synthesis of a novel water-stable nickel-based metal-
organic framework (Ni-MOF) with a Co-MOF, as well as the dual Ni/Co-MOF-reduced …

The origin and assignment of the complex main and satellite X-ray photoelectron
spectroscopy (XPS) features of the cations in ionic compounds have been the subject of …

This study was mainly aimed at constructing an amorphous NiO modified gC 3 N 4 non-
noble metal heterojunction photocatalyst for enhanced visible-light hydrogen evolution. The …

One approach to accelerate the stagnant kinetics of both the oxygen reduction and evolution
reactions (ORR/OER) is to develop a rationally designed multiphase nanocomposite, where …

NiO has been analyzed by X-ray diffraction (XRD), X-ray absorption fine structure (XAFS)
analysis, and X-ray photoelectron spectroscopy (XPS) for bulk-scale and nanosized …
