A research team at the University of Helsinki, led by Prof. Pedro Camargo, has developed groundbreaking nanoparticle technology that could revolutionize green hydrogen and ammonia production. By combining plasmonic and catalytic materials in bimetallic nanoparticles, the team leveraged sunlight to drive chemical reactions more efficiently and selectively. This innovation, detailed in the Angewandte Chemie International Edition, demonstrated a significant increase in hydrogen and ammonia production rates with improved reaction selectivity under light conditions. The strategic placement of platinum on gold nanoparticles played a vital role in accelerating reactions when exposed to light. Prof. Camargo highlighted the potential for designing new materials using minimal noble metals to achieve superior results, paving the way for cost-effective and scalable green technologies. The University of Helsinki has filed a patent for the technology and received a Research to Business project grant from Business Finland to further develop and commercialize the nanoparticle technology. This funding aims to transition the innovation from the lab to real-world applications, contributing to the global shift towards greener energy solutions.
