Exploring renewable carbon and energy resources is essential for our sustainable development. Biomass, as the most abundant renewable carbon source, and solar energy, as a clean and inexhaustible energy source, offer promising avenues for advancement. Our research focuses on developing novel electrochemical and photochemical systems to maximize the efficient utilization of biomass and solar energy. This presentation will highlight our recent achievements, including hybrid electrocatalytic systems for biomass valorization via bipolar hydrogenation and two-photon-absorbing photocatalysts designed for diverse organic transformations under red and near-infrared light irradiation.
