چکیده

The immobilisation of electrocatalysts for CO2 reduction onto light harvesting semiconductors is proposed to be an important step towards developing more efficient CO2 reduction photoelectrodes. Here, we report a low cost nickel cyclam complex covalently anchored to a metal oxide surface. Using transient spectroscopy we validate the role of surface immobilisation on enhancing the rate of photoelectron transfer. Furthermore [Ni(1,4,8,11-tetraazacyclotetradecane-6-carboxylic acid)](2+) (2) is shown to be a very active electrocatalyst in solution.

Distance dependent charge separation and recombination in semiconductor/molecular catalyst systems for water splitting

The immobilisation of molecular catalysts on semiconductors for solar fuel production is an attractive strategy to exploit electrocatalysts in a heterogeneous photocatalytic environment. Efficient H2 production in such hybrid systems requires effective electronic coupling between the light harvesting unit and the electrocatalyst. Current examples based on non-precious metal complexes include Co...

Improving the Photocatalytic Reduction of CO2 to CO through Immobilisation of a Molecular Re Catalyst on TiO2

The photocatalytic activity of phosphonated Re complexes, [Re(2,2'-bipyridine-4,4'-bisphosphonic acid) (CO)3(L)] (ReP; L = 3-picoline or bromide) immobilised on TiO2 nanoparticles is reported. The heterogenised Re catalyst on the semiconductor, ReP-TiO2 hybrid, displays an improvement in CO2 reduction photocatalysis. A high turnover number (TON) of 48 molCO molRe(-1) is observed in DMF with the...

Organic template-free synthesis of Ni-ZSM-5 nanozeolite: a novel catalyst for formaldehyde electrooxidation onto modified Ni-ZSM-5/CPE

A novel modified Ni-ZSM-5 nanozeolite was fabricated via an organic template-free hydrothermal route. The average particle size of Ni-ZSM-5 nanozeolite was calculated to be 85 nm by scanning electronic microscopy. Then, Carbon paste electrode (CPE) was modified by Ni-ZSM-5 nanozeolite and Ni2+ ions were then incorporated to the nanozeolite matrix. Electrochemical behavior of this electrode was ...
