An array of Pd, Fe and Ir exchanged β-zeolites were synthesized, fully characterized, and their catalytic activity evaluated in converting bio-derived compounds to value-added platform chemicals.

Lignocellulosic biomass is becoming a viable alternative or a complementary source for obtaining petroleum-derived products such as fuels, polymers and fine chemicals, among others.

Besouros predadores da família Histeridae foram coletados através do uso de armadilhas "pitfall" iscadas com massa fecal fresca de bovinos instaladas em área de pastagem em Piracicaba, SP. Coletaram-se durante o período de 15 de abril de 1995 a 17 de fevereiro de 1996, quatro espécies identificadas como Hister punctifer, Phelister panamensis, P. haemorrhous e P. rufinotus. A espécie P. panamensis é um importante predador de ovos e larvas de Haematobia irritans e representou 72,93% do total de insetos coletados.

The development of more efficient and greener catalytic strategies for the upgrading of biomass to value-added chemicals is crucial to achieve a more sustainable future. In recent years, cutting-edge single-atom...
