A cleaner approach towards magnetically assisted-electrolysis of biodiesel production using novel MnFe2O4@sawdust derived biochar nanocatalyst and its performance on a CI engine
The present research focused on the synthesis of nanocatalyst using manganese ferrite impregnated on sawdustderived biochar (MnFe2O4@biochar) through single-stage hydrothermal process and was subsequently employed as a recoverable and highly reactive catalyst in the conversion of edible waste oil (EWO) into biodiesel. Diverse characterization techniques were employed to assess the structural attributes of both MnFe2O4 […]

How do different feedstocks and pyrolysis conditions effectively change biochar modification scenarios? A critical analysis of engineered biochars under H2O2 oxidation
Biochar oxidation is known as a modification method to enhance the beneficial sorption characteristics of biochar. To explore this, a comparative physio-chemical analysis of non-oxidized and oxidized biochar with hydrogen peroxide (H2O2) was conducted using different feedstocks. Biochars were pyrolyzed at temperatures of 350, 450, and 550 degrees C and were derived from wheat straw, […]

Electrochemical activation of biochar and energy-saving hydrogen production by regulation of biochar-assisted water electrolysis
Biochar-assisted water electrolysis (BAWE) has the potential to reduce the electricity consumption of hydrogen production. However, prolonged electrolysis leads to over-oxidation of biochar, reduced reactivity, and decreasing hydrogen production at cathode. Herein, we proposed the electrochemical activation of biochar via limited biochar oxidation reaction (BOR) and hydrogen evolution reaction (HER) in BAWE process, and the […]

Techno-economic assessment of blue and green ammonia as energy carriers in a low-carbon future
Abstract Ammonia is an industrial chemical and the basic building block for the fertilizer industry. Lately, attention has shifted towards using ammonia as a carbon-free energy vector, due to the ease of transportation and storage in liquid state at −33 °C and atmospheric pressure. This study evaluates the prospects of blue and green ammonia as future […]

Recent progress in Green Ammonia: Production, applications, assessment; barriers, and its role in achieving the sustainable development goals
Abstract Fossil fuels are no longer accepted as the sole energy source with their environmental impacts and fluctuating price. Green hydrogen is considered a potential candidate for fossil fuel soon—however, hydrogen is facing the challenges of storage and transportation. Green ammonia, with its ease of transport and storage, is another promising alternative. Decarbonizing ammonia production […]
