“…In 1801, an English chemist, Charles Hatchett, described the discovery of an element similar to tantalum and named it columbium [ 3 ]. In 1809, William Hyde Wollaston (English chemist) mistakenly concluded that tantalum and columbium were identical [ 4 ]. A German chemist, Heinrich Rose, established in 1846 that the tantalum ores contained a second element which was baptized as niobium [ 5 ].…”

The world scenario regarding consumption and demand for products based on fossil fuels has demonstrated the imperative need to develop new technologies capable of using renewable resources. In this context, the use of biomass to obtain chemical intermediates and fuels has emerged as an important area of research in recent years, since it is a renewable source of carbon in great abundance. It has the benefit of not contributing to the additional emission of greenhouse gases since the CO2 released during the energy conversion process is consumed by it through photosynthesis. In the presented review, the authors provide an update of the literature in the field of biomass transformation with the use of niobium-containing catalysts, emphasizing the versatility of niobium compounds for the conversion of different types of biomass.

“…1,2 Em 1844, o mineralogista e químico Heinrich Rose isolou e renomeou o então colúmbio de nióbio, em referência a personagem da mitologia grega Níobe, filha do rei Tântalo. 3 A duplicidade do nome perdurou até 1950, ano em que a IUPAC definiu oficialmente o nome nióbio para o metal de transição. 4 Três anos após a oficialização do nome nióbio, o geólogo Djalma Guimarães encontrou os primeiros cristais de pandaíta (Ba,Sr) 2 (Nb,Ti,Ta) 2 (O,OH,F) 7 no município de Araxá, em Minas Gerais.…”
