【Abstract】 Hydrogen energy is an important carrier to achieve green and low-carbon transformation with energy terminals. In order to ensure the safe and high-quality development of the hydrogen energy industry, various hydrogen leak detection technologies have been developed. Tungsten trioxide(WO3) is the most commonly used color-changing material for hydrochromic leakage detection. The preparation methods of WO3 hydrochromic materials were discussed, and the properties of WO3 hydrochromic materials under different preparation methods were compared and analyzed. In addition, it was suggested that a quantitative characterization test standard should be established around the indexes such as coloring and bleaching degree, response time and rate, recovery time and rate, stability and repeatability of hydrogen sensitive color-changing materials, so as to promote the performance evaluation and industrial application of hydrogen sensitive color-changing materials. Finally,the future research focus of WO3 hydrochromic materials and hydrogen leakage detection technology was prospected.更多还原
