Special Issue Information

Dear Colleagues,

Global climate change is one of the largest nontraditional challenges to the environment and human development. Therefore, reducing greenhouse gas emissions has become the focus of international politics and cooperation for economic development. Among emerging green technologies, photochemical system has been viewed as a promising approach to reduce CO2 emission and achieve the goal of carbon neutrality, which utilizes solar energy and converting water/CO2 to hydrogen or carbon-based fuels. To date, numerous photochemical systems have been developed to obtain a viable solar-to-fuel production with decent energy efficiency, including photocatalytic, photovoltaic-electrochemical, photoelectrochemical, solar thermochemical, etc. However, more efforts in both the scientific and engineering aspects are still needed to meet the requirement of industrial implementation.

Topics of interest include, but are not limited to:

  • Calculation of thermal, photo- or electrocatalysis behavior on the basis of quantum mechanical considerations;
  • Multi-physics simulation framework for photochemical systems;
  • Materials for photocatalytic, photovoltaic–electrochemical, photoelectrochemical, solar thermochemical, and other emerging systems;
  • Prototype devices for water splitting or CO2

A novel hybrid structure of bimetallic dicyanamide decorated BiVO4 is developed via a simple method to accelerate interfacial water oxidation kinetics. Two types of bimetallic dicyanamides, CoNi(dca)2 and CoFe(dca)2, are coated on BiVO4 photoanodes and are found to exhibit far more enhanced PEC performance than Co(dca)2 or Ni(dca)2 as cocatalysts. The successful deposition of metal dicyanamides on BiVO4 photoanodes is confirmed by physical characterizations including X-ray photoelectron spectroscopy (XPS). The optimized Co0.9Ni0.1(dca)2/BiVO4 photoanode exhibits the highest photocurrent density of 2.58 mA/cm2 at 1.23 V vs. RHE under 100 mW/cm2 AM 1.5 G irradiation, which is 2.5 times that of bare BiVO4. The substantial enhancement of PEC performance can be ascribed to the advantageous interfacial charge transfer and improved charge injection efficiencies. This work presents a feasible strategy using different types of bimetallic dicyanamides to design a modified BiVO4-based photoanode system for enhanced water oxidation efficiency. Full article
