Introduction

    The Dong Research Group (Environmental and Energy Catalysis Lab) at the Chongqing Technology and Business University, led by Prof Dong Fan, aims to synthesize, self-assemble, and functionalize novel, low-cost, efficient and durable photocatalysts and electrocatalyst for applications in energy and environment.
    On one hand, we are committed to the development of photocatalysis for the degradation of environmental pollutants (nitrogen oxide and volatile organic compounds) and the exploration of photocatalytic reaction mechanisms. Specifically, our group focuses on the development semimetal bismuth, bismuth-based photocatalysts, graphitic carbon nitride and lanthanum-based photocatalysts to meet the challenges of environment pollution and energy shortage. Simultaneously, we reveals the reaction pathway of photocatalytic reaction process via a novel in situ DRIFTS-based strategy to understand the mechanism of photocatalytic reaction, evaluate the risks in generation of toxic intermediates, optimize the photocatalyst performance and advance the development of photocatalytic technology for environmental remediation. Furthermore, we proposes a highly combined theoretical (DFT calculations) and experimental method to designed synthesis of highly efficient visible light driven photocatalysts, illustrate the geometric structures of photocatalyst at the atomic level, and reflect the migration and transformation of photo-generated carriers. With such approaches, these photocatalysts are able to predictably and efficiently convert solar energy into chemical energy for environmental remediation.
    On the other hand, we are developing electrocatalysis for environmental remediation especially for water purification and exploring electrocatalytic reaction mechanisms. Typically we mainly develop Pd-based nanocomposite electrocatalysts. Our group devote to understand the mechanism of Electrocatalytic hydrogenation and hydrogenolysis (ECH), in which the way to dispose persistent contaminants such as oxidizing anion is a transformation of adsorbed hydrogen (H*ad) reduced by electrode. We seek the effective strategy to optimize ECH performance. The combination of density functional theory (DFT) and experiment is also applied to help establish the relationship between Pd electronic structure and its performance and design the synthesis of highly performed electrocatalysts. Then electric energy can be converted into chemical energy through electrocatalysts for environmental decontamination.
    In addition, our approach is multidisciplinary as it involves concepts from environmental engineering, chemical engineering, electrical engineering, materials science, physics and catalysis.
