At present, our modern world heavily depends on fossil fuels. Yet, the most pressing challenge ahead of humanity is the gradual shift from fossil fuels to renewable sources for our energy needs. Solar energy emerges as a pivotal clean and renewable energy source. Despite its significance, challenges such as low energy density, fluctuations due to day-night cycles and seasonal variations, and storage complexities severely impede its large-scale practical application. Traditional solar cells and wind power exhibit intermittency and fluctuations, leading to asynchronous electricity generation and utilization, underscoring the urgency to address energy storage issues.
The fields of photocatalysis and electrocatalysis offer immense promise in addressing energy and environmental concerns. For example, photocatalysis directly harnesses solar light to decompose water, yielding hydrogen and converting solar energy into storable chemical energy—specifically, hydrogen energy. Additionally, photocatalysis has the potential to convert carbon dioxide into methane, methanol, and other hydrocarbon fuels, contributing to achieving carbon neutrality. These solar energy-derived fuels—hydrogen, methane, and methanol, among others—are collectively termed solar fuels.
In recent years, research on solar fuels has steadily gained prominence in fields like photocatalysis and electrocatalysis. In light of this, the first International Workshop on Solar Fuel (IWSF) was held at Holiday Inn Wuhan Riverside, Wuhan, China from December 10-13, 2021. With continuous advancements and a growing community of researchers in the realm of solar fuels, we are pleased to announce the second iteration, the International Workshop on Solar Fuel (IWSF2), scheduled for April 12-15, 2024, at Holiday Inn Wuhan Riverside, Wuhan, China. This conference is jointly organized by China University of Geosciences (Wuhan), Dali University, Jilin Institute of Chemical Technology, Changsha University, Wuhan University of Technology, and other institutions. The primary aim of this workshop is to provide an eminent platform for academic discourse in the domain of solar fuels, facilitating the exploration of scientific challenges in this rapidly evolving field and fostering direct interactions among researchers from diverse nations and regions.
The thematic focus of this workshop includes, but is not restricted to:
• Photocatalytic hydrogen production
• Photocatalytic CO2 reduction
• Photocatalytic environmental purification
• Novel photocatalytic materials
• S-scheme heterojunctions
• Electrocatalytic hydrogen production
• Electrocatalytic CO2 reduction
• And other pertinent topics.
