This review begins with the historical development of the theories of acidity and of the preparation of acids. The historical aspects of acid catalysis and catalysts are also briefly surveyed. The fundamentals concerning acidity and acid catalysis in liquid phases and at the solid-liquid interfaces are discussed. The factors determining acidity...

Solid acids are the green alternative for heterogeneous acid catalysis, in particular for industrial processes exploiting biomass. Niobium-phosphorus oxides are valid candidates owing to their specific acidic properties and tolerance to water, on the other hand their synthesis often involves hazardous precursors and complex multistep...
