Influence of lignin and cellulose from termite-processed biomass on biochar production and evaluation of chromium VI adsorption.

The increasing water contamination by toxic heavy metals, particularly hexavalent chromium, has become a significant environmental concern. This study explores the pyrolysis of termite-processed biomass, specifically Pinus elliottii particleboard and its termite droppings (TDs), to produce biochar and its application for chromium (VI) adsorption. Termite droppings, rich in lignin, and particleboard, rich in cellulose, were pyrolyzed at various temperatures to assess the effect of biomass composition on biochar properties.

Visible-light Bi-Fe-Nb-O photoanodes for solar-light driven hydrogen production.

Currently, CO emission is the main cause of climate change and its various related environmental impacts. Therefore, we have as a prime the development of clean sources of energy. The hydrogen economy is very attractive in this regard, however, when generated from the methane reform, there are also large-scale CO emissions.
