摘要
Electroreduction of CO_(2) to formic acid has attracted extensive attention,because it is a promising strategy to re-utilize CO_(2) and reduce greenhouse gas emissions that may favor the mitigation of energy and environment issues.Although great efforts have been made to tune the structure and composition of catalysts aiming to improve CO_(2) conversion efficiency,seldom studies have been focused on the support regulation.In this work,ordered,porous TiO_(2) nanotube arrays have been used as model support to study the impact of pore structure for CO_(2) electrochemical reduction.It has been revealed that Pd supported on TiO_(2) nanotube arrays substrate exhibits enhanced performance towards CO_(2) reduction,showing a higher formate Faradaic efficiency of 20%over than Pd supported on TiO_(2) film substrate.This study will shed new light on the design and synthesis of efficient catalysts by tuning the morphology of support for CO_(2) conversion.
