• acid sites and Brønsted acid sites followed by NO and O2. Langmuir–Hinshelwood mechanism The Langmuir–Hinshelwood mechanism occurs when two molecules of NO and NH3 are adsorbed to the catalyst surface and then bonded together to form N2 and H2O. Liu et al. [21] examined the Langmuir–Hinshelwood

• , following the Langmuir–Hinshelwood mechanism. Shi et al. [25] used DRIFT to investigate the chemical reaction of reactants with the Lewis acid site and Brønsted acid site to improve activity at low temperature. Chen et al. [26] found that CeO2 provided both acid sites, while WO3 helped in increasing the

• degradation of RhB was modeled with the Langmuir–Hinshelwood mechanism, which is most commonly used to explain the kinetics of heterogeneous photocatalytic reaction [30]. It is expressed as follows: where r is reaction rate, k is the reaction rate constant, K is the adsorption coefficient, t is the time and
