Challenges in Syngas Fermentation for Bioethanol Production: Syngas Composition

open access: yesEngineering Chemistry, 2023
Energy challenges in developing countries are more significant if they continue to use fossil materials and have an impact on air quality. Lignocellulosic biomass can be an alternative to new renewable sources to replace fossil materials. Indonesia produces various sources of lignocellulosic biomass, which can be used in multiple energy sources such as

The Influence of Co-Firing Coal with Biomass Syngas on the Thermodynamic Parameters of a Boiler

open access: yesApplied Sciences, 2023
Biomass syngas can be considered as a supplementary fuel to partially substitute coal, which is beneficial to CO2 emission reduction. For the case study, the influences of co-firing typical biomass syngas (gasification from palm, straw, and wood) with ...

Heterogenised Molecular Catalysts for the Reduction of CO2 to Fuels

open access: yesCHIMIA, 2015
CO2 conversion provides a possible solution to curtail the growing CO2 levels in our atmosphere and reduce dependence on fossil fuels. To this end, it is essential to develop efficient catalysts for the reduction of CO2.

Metal-encapsulated organolead halide perovskite photocathode for solar-driven hydrogen evolution in water

open access: yesNature Communications, 2016
Lead-halide perovskites are sensitive to humidity, which limits their use in water splitting applications. Here, the authors protect the perovskite layer with Field’s metal, driving photoelectrocatalytic hydrogen evolution in an aqueous solution for ...
