The high price of noble metal resources limits its commercial application and stimulates the potential for developing new catalysts that can replace noble metal catalysts. Tungsten-based catalysts have become the most important substitutes for noble metal catalysts because of their rich resources, friendly environment, rich valence and better adsorption enthalpy. However, some challenges still hinder the development of tungsten-based catalysts, such as limited catalytic activity, instability, difficult recovery, and so on. At present, the focus of tungsten-based catalyst research is to develop a satisfactory material with high catalytic performance, excellent stability and green environmental protection, mainly including tungsten atomic catalysts, tungsten metal nanocatalysts, tungsten-based compound nanocatalysts, and so on. In this work, we first present the research status of these tungsten-based catalysts with different sizes, existing forms, and chemical compositions, and further provide a basis for future perspectives on tungsten-based catalysts.
贵金属资源的高价格限制了其商业应用，刺激了开发可替代贵金属催化剂的新型催化剂的潜力。基于钨的催化剂由于其丰富的资源、友好的环境、丰富的价态和更好的吸附焓，已成为最重要的贵金属催化剂替代品。然而，一些挑战仍然阻碍了基于钨的催化剂的发展，例如有限的催化活性、不稳定性、难以回收等。目前，基于钨的催化剂研究的重点是开发一种具有高催化性能、优异稳定性和绿色环保的满意材料，主要包括钨原子催化剂、钨金属纳米催化剂、钨基化合物纳米催化剂等。在这项工作中，我们首先介绍了这些具有不同尺寸、存在形式和化学成分的基于钨的催化剂的研究现状，并为基于钨的催化剂的未来展望提供了依据。
