Semarang, 30 September 2025 — The Department of Chemistry, Faculty of Science and Mathematics, Universitas Diponegoro (UNDIP) held a webinar titled “Heterogeneous Catalysis and Photocatalysis in CO₂ Utilization and Hydrogen Production” via Zoom Meeting. The event was attended by students, lecturers, and researchers from various institutions in Indonesia and abroad with interests in energy and advanced materials.
The webinar featured Dr. Hasliza Bahruji, a lecturer and researcher at the Centre of Advanced Material and Energy Sciences, Universiti Brunei Darussalam, moderated by Alvin Romadhoni Putra Hidayat, S.Si., M.Si. In her scientific presentation, Dr. Hasliza underscored the urgency of innovations in heterogeneous catalysis and photocatalysis to address climate change and the need for sustainable energy. Catalytic approaches, she noted, open opportunities to utilize carbon dioxide (CO₂) as a value-added feedstock while supporting hydrogen (H₂) production as a clean energy source for the future.
Dr. Hasliza explained that CO₂ is not merely a waste gas; it can be used as a carbon feedstock to produce fuels such as methanol and dimethyl ether (DME) through catalytic processes. The research presented demonstrated the effectiveness of PdZn/ZnO–TiO₂-based catalysts in converting CO₂ to methanol with high activity and stability. She also discussed the use of TiO₂ and g-C₃N₄ photocatalysts in water splitting and biofuel photoreforming to produce H₂ using visible light.
This event provided up-to-date insights into the application of advanced catalytic technologies for sustainable CO₂ utilization and the development of an environmentally friendly hydrogen supply chain. It is also expected to strengthen cross-institutional research collaboration and accelerate green energy development.
The Faculty of Science and Mathematics at Universitas Diponegoro reaffirms its commitment to advancing research and downstreaming knowledge in materials and clean energy. FSM UNDIP will continue to open avenues for national and international collaboration, promote knowledge transfer, and deliver science-based solutions to support a sustainable energy transition in Indonesia.
