Heusler alloys are a series of well-established intermetallic compounds with abundant structure and elemental substitutions, which are considered as potentially valuable catalysts for integrating multiple reactions owing to the features of ordered atomic arrangement and optimized electronic structure. Herein, a nanoporous copper titanium tin (np-CuTiSn) Heusler alloy is successfully prepared by the (electro)chemical dealloying transformation method, which exhibits high nitrate (NO) reduction performance with an NH Faradaic efficiency of 77.14 %, an NH yield rate of 11.

Aquatic pollution refers to any water that has been used and discarded in different water bodies by industrial and commercial activities which contains a wide range of toxic substances and required treatment so that water can be safely reused for various purposes. In present paper, polymer polyvinylpyrrolidone (PVP) and plant Tinospora Cordifolia (T. Cordifolia) encapsulated dual doped cobalt-copper titanium dioxide nanoparticles (Co-Cu TNPs) has been synthesized via microwave-assisted method for the degradation aquatic pollutant dyes: Methyl Orange (MO) & Methylene Blue (MB).

A highly active electrocatalytic electrode for nitrate reduction was prepared by the electro-deposition of palladium onto a copper electrode. The capacity of nitrate reduction by a palladium-modified copper electrode has been studied using cyclic voltammetry (CV). The existence of a reduction peak at -0.
