Ni-N codoped SnO2/Fe2O3 nanocomposite as advanced bifunctional photocatalyst for simultaneous photocatalytic redox conversion of Cr(VI) and As(III)

TLDR
In this paper, the performance of photocatalytic Cr(VI) reduction and As(III) oxidation in single and co-existing systems was systematically evaluated, and the results exhibited that by employing Ni/N-codoped SnO2/Fe2O3 nanocomposites, the simultaneous photocatallytic redox conversion of Cr (VI) and As (III) were remarkably accelerated under visible light irradiation.
Abstract
In this work, the performance of photocatalytic Cr(VI) reduction and As(III) oxidation in single and co-existing systems was systematically evaluated. The results exhibited that by employing Ni/N-codoped SnO2/Fe2O3 nanocomposites, the simultaneous photocatalytic redox conversion of Cr(VI) and As(III) were remarkably accelerated under visible light irradiation. The highest efficiency of Cr(VI) reduction and As(III) oxidation was found to be 99 and 96% with recyclability of 96.1 and 93.7% after five cycles over 8Ni/N-codoped SnO2/Fe2O3 nanocomposite under 90 min irradiation in the co-existing system, respectively. These findings open a new path to design high-performance photocatalysts for the synergetic photocatalytic redox conversation and removal of Cr(VI) and As(III) under visible light irradiation.

Langmuir–Hinshelwood kinetics – A theoretical study

TL;DR: In this article, it was shown that it is impossible and inappropriate to approximate the Langmuir-Hinshelwood kinetics to zero-order kinetics, and therefore, it is not possible to approximate it to zero order kinetics.
