A composite multi-cation high-entropy catalyst, which integrates the concept of high-entropy compounds into traditional metal oxide catalysts, such as spinel, perovskite, and fluorite structure. By the combination of photoelectric, piezoelectric, and ferroelectric materials with the characteristic high-entropy oxides. The high-entropy composite piezoelectric catalysts could become a promising technology for clean energy applications, such as organic dye degradation and hydrogen generation.

Metal-organic framework is a kind of regular porous material which is self-assembled by metal ion centerorganic ligand framework. I used the metal-organic framework as a templateprecursor to successfully develop a low-cost bimetallic phosphide, which exhibits excellent water splitting hydrogen production performance. The on-site real-time change experiment technology provided by Taiwan Photon Source is a great weapon for real-time detection of active sitesreaction centers during the development of key catalyst materials.

This invention provides a method for synthesis a catalyst for catalyzing hydrogenation of CO2 to methanol. The precipitation process was controlled at 70 oCaging for 1.5 hour. The CuO: ZnO: Al2O3 weight ratios are 7: 3: 1. The particle size of CuO is less than 5 nm. The reaction is carried at 50 bar250 oC, CO2/H2= 1/3. Adding hydrophobic fumed silica, water is expelled from catalyst surface,the reaction can shift to product side. Therefore the CO2 conversion can reach 90 thermodynamic equilibrium conversion, methanol selectivity is greater than 95.

The goal of this project is to study "low-temperature magnesium hydrogen storage materials and energy storage applications". Mg hydrogen storage materials with a hydrogen storage capacity of 5.0 wt% is developed,and their dehydrogenation rate at 250℃ will be significantly enhanced using a forcible pump. The Mg hydrogen storage powders are inserted into a tank for cyclic hydrogenation-dehydrogenation tests. The H2 gas desorbed from the tank is supplied to a high-temperature proton exchange membrane fuel cell (HT-PEMFC,160℃) for power generation.
