Advanced Bifunctional Catalyst （OER&ORR）Development for Zinc-Air Battery Systems (currently working on)

◆ Engineered FeCoNi-based medium-entropy alloy (MEA) catalysts addressing critical challenges in zinc-air batteries: high overpotential (ΔE > 0.85V between OER/ORR) , achieving record ΔE = 0.65V (OER@10mA/cm²: 1.54V vs. RHE; ORR@Half-wave potential: 0.90V)
◆ Developed hierarchical architecture through wet-impregnation & annealing

◆ Combined DFT calculations (VASP) with experimental validation (working on)

• Identified the optimal ORR active centers
• Demonstrated Fe-Co-Ni synergy reduces OER rate-determining step barrier
• Charge density difference analysis revealed d-band center modulation mechanism

• Prepared engineering scopes of work for piping modifications and updated technical diagrams, including P&ID, ISO, and PFD diagrams
• Ensured compliance with NWR technical standards (e.g., hydrotesting and torque calculations)
• Conducted field investigations of welding and injection points in the pipe system, contributing to materials engineering assessments
• Streamlined documentation processes to align with NWR’s document control standards

• Contributed to the Jinjitan Railway Project by designing super-elevation on railway curves with varying turning radii and presenting the necessity of transition curves to the project team
• Conducted data analysis for the Xuzhou Logistics Industrial Park Project, visualizing results through histograms, bar graphs, and dot plots to evaluate port handling capacities and future project potential
• Created I-beam drawings using SolidWorks, which were approved for fabrication by government authorities
• Drafted project and personnel placement contracts using advanced Microsoft Word skills
