Copper-based non-precious metal heterogeneous catalysts for environmental remediation

Abstract

This paper presents a detailed review of copper-based catalysts used in wide-ranging environmental remediation, including gas, liquid and solid phase pollutant elimination. Latest advances in the remarkable catalytic activity of copper-based catalysts, including bulk CuOx, supported CuOx, and solid solution CuOx-X are emphasized. The structure-activity relationships among the crystal structure, morphology, catalyst support, and catalytic performance in specific catalytic reactions for environmental remediation are discussed. Furthermore, current obstacles faced by Cu-based catalysts and potential strategies to address them have been proposed, which may aid the future research and development of highly efficient Cu-based non-precious metal catalysts.
