A mesoporous carbon (CMC) has been treated under acidic conditions (32.5 wt% HNO3 at 10 °C or 40 °C) to prepare two new carbon samples (HCMC10 and HCMC40), which developed higher acidity in terms of quantity of sites and surface acid strength. The

Niobium oxophosphate acid catalyst (NbP) has great success in aqueous heterogeneous catalysis, in particular for carbohydrate biomass valorization, thanks to the water-tolerant acid properties of the LA (Lewis) and BA (Bronsted) sites. Attempts to ta

Photocatalytic reactions promoted by TiO 2 can be affected by a large number of oxide features ( e.g. surface area, morphology and phase composition). In this context, the role played by the surface characteristics ( e.g. surface acidity, wettability
