Sol-gel synthesized NixFe3−xO4 for thermochemical conversion of CO2
(
Elsevier B.V.
, 2019 , Article)
To identify the best suitable metal oxide (MO) to split H2O/CO2, it is critical to investigate the formation of O2 vacancies during thermal reduction (TR) step and the re-oxidation of the MOs via H2O or CO2 splitting (CS) ...
Intermediate ozonation to enhance biogas production in batch and continuous systems using animal dung and agricultural waste
(
Elsevier Ltd
, 2017 , Article)
Agricultural waste and animal manure (dung) pose an environmental threat in developing countries. This investigation focused on the possible use of such waste as an energy source in the form of biogas produced via anaerobic ...
