Hydrogen energy is one of the most promising clean energy sources in the 21st century. As an important way to achieve the global "carbon peaking and carbon neutrality" goal, developing efficient hydrogen energy conversion technologies has become a global research hotspot. Developing electrocatalysts with high activity, selectivity, and stability is a key challenge for the commercialization of hydrogen energy converter components.

Based on the corrosion induction strategy, Tian has developed a new method for synergistic regulation the coordination and stress effects of low-platinum based alloys. He has developed a one-dimensional bunched Pt-Ni alloy nanocages catalyst with excellent electrocatalytic performance, significantly improving the output power and service life of hydrogen fuel cells. He also constructed a new platinum-based core-shell structure catalyst with an ultra-thin platinum layer as the shell, revealing the stability regulation mechanism of core-shell structure, and demonstrating excellent stability performance in direct electrolysis of seawater for hydrogen production and seawater electrolysis cell testing.

Tian also proposed the "movable type printing method" to synthesize high entropy single atom catalysts, and established a new system of single atom catalysts with multiple metal active centers, providing new ways for the design and synthesis of multi active centers and multifunctional electrocatalysts.

In the long run, he will focus on the design, performance regulation, and device development of highly stable catalysts for seawater electrolysis. By coupling ocean renewable energy to directly electrolyze seawater for hydrogen production, he's able to achieve the conversion of fluctuating and intermittent blue energy into a stable hydrogen energy supply system.
