“…Bioethanol is an increasingly available and economical hydrogen vector with a global annual yield of 109.8 billion liters in 2019 4 , which is formed by fermentation of renewable biomass. Bioethanol reforming to H 2 can provide an appealing solution for meeting the vast demand of carbon-neutral economy on green hydrogen.…”

Light-driven hydrogen production from renewable liquid biomass derivatives rather than fossil fuels offers an ideal path towards carbon neutrality.1–3 It is often however operated under an anaerobic condition with the limitations of sluggish kinetics and severe coking. Herein, a disruptive air-promoted strategy is explored for exceptionally efficient and durable light-driven hydrogen production from bioethanol over a core/shell Cr2O3@GaN nanowires semiconducting architecture. Owing to the unique catalytic attributes of Cr2O3@GaN, bioethanol is energetically favorable to be adsorbed on the Cr2O3@GaN interface, followed by dehydrogenation toward acetaldehyde and protons by photoexcited holes. The released protons are then consumed for H2 evolution by photogenerated electrons. After that, O2 can be evolved into active oxygen species and promote the continuous deprotonation and C-C cleavage of the key C2 intermediate, thus significantly lowering the reaction energy barrier of hydrogen evolution from bioethanol and removing the carbon residual with inhibited bioethanol overoxidation. As a result, hydrogen is produced at a high rate of 76.9 mole H2 per gram Cr2O3@GaN per hour by only feeding bioethanol, air, and light. Notably, an unprecedented light-to-hydrogen efficiency of 17.6% is achieved under concentrated light illumination of 7 W∙cm-2. A distinguished turnover frequency of > 2,314,000 mole H2 per mole Cr2O3 per hour, in conjunction with a superior stability of 180 hours, leads to the achievement of a record-high turnover number of 266,943,000 mole H2 per mole Cr2O3. The simultaneous generation of aldehyde from bioethanol dehydrogenation enables the process more economically promising.

Alternative fuels have the potential to reduce exhaust emissions in the transportation sector. In this study, the effects of oxygenated fuels on the performance and emissions of a gasoline single-cylinder spark-ignition engine have been investigated experimentally. Experiments were conducted using a DIDACTA-T85 testbed under full load conditions and variable engine speed. Performance tests were performed by measuring the brake torque, brake power, brake mean effective pressure (BMEP), brake specific fuel consumption (BSFC), and brake thermal efficiency (BTE). The tested fuel blends were G0, E10, A10, and M10. G0 represented the base fuel and pure gasoline. E10, A10, and M10 were represented by a 10% volume of ethanol, acetone, and methanol in gasoline respectively. Results showed that M10 produced better engine performance in terms of brake torque, brake power, and BMEP, while E10 performed better results in terms of BSFC and BTE. A10 gave the lowest value in NOx emission at all engine speeds. On the other hand, it increased the NOX emission for E10 and M10 blends. This study showed that oxygenated fuel blends significantly reduced carbon monoxide emission at all engine speeds whereas carbon dioxide emission was higher at the highest engine speed.

“…Reduction in the production cost and improvement in cellulases yield could also be achieved using appropriate and low cost carbon and nitrogen sources in the formulation of fermentation medium (Shanmugam R et al, 2022). Therefore, the use of abundantly available and cost-effective agricultural by products must allow reduction of the overall production cost of the decomposing enzymes which could be resolved by isolating cellulolytic strains with high levels of cellulases as well as xylanase productivity, optimizing fermentation conditions while making useof cheaper agricultural and industrial substrates as carbon or nitrogen source in the fermentation medium (Anil K et al, 2014, Seema Devi et al,2015, 2016.…”

In this study the filamentous fungi Trichoderma atroviride AD-130 was evaluated for production of cellulases as well as xylanase. An attempt has been made to optimize the cultural and nutritional conditions for cellulases and xylanase production by Trichoderma atroviride AD-130 under submerged fermentation. The lignocellulosic biomass of Saccharum munja was used as carbon source for cellulases and xylanase production. Whole fermentation process was carried out in 250 mL Erlenmeyer flasks with agitation speed of 170rpm. The maximum titers of cellulases (FPase 1.01 U mL-1, CMCase 2.69 U mL-1, b-glucosidase 0.82 U mL-1) and xylanase (82.99 U mL-1) were obtained on 5th and 4th day respectively when Trichoderma atroviride AD-130 was grown at initial medium having pH 6.0 at 30°C using 2.0% (w/v) Saccharum munja biomass as substrate.
