Title:

Optimization of Anchoring Isonicotinic acid on TiO2 NP for Applications in Dye Sensitized Photocatalysis

In 2021, green hydrogen was $9.65/kg more expensive than gasoline. DSSCs are already a low-cost photovoltaic, but the cost can be further reduced by optimizing different components. Anchoring groups of molecular catalysts have been identified as one area with the opportunity of cost reduction. In this poster it is shown that a self-assembled and low-cost molecular catalyst reduces cost 400-fold. CoP was thought to have greater photocatalytic activity than CoISO because it can bind strongly to the surface of TiO2 through its phosphonic acid anchoring group. Results show CoISO produces hydrogen at a similar rate to CoP. This research aids in decreasing the cost of DSSCs to close the gap between green energy and fossil fuels.
