Greenly Synthesized Conducting Polymer Nanotunnels with Metal-Hydroxide Nanobundles in Single Dais for Unmitigated Water Oxidation.

Electrochemical water splitting required efficient electrocatalysts to produce clean hydrogen fuel. Here, we adopted greenway coprecipitation (GC) method to synthesize conducting polymer (CP) nanotunnel network affixed with luminal-abluminal CoNi hydroxides (GC-CoNiCP), namely, GC-CoNiCP, GC-CoNiCP, and GC-CoNiCP. The active catalyst, GC-CoNiCP/GC, has low oxygen evolution reaction (OER) overpotential (307 mV) and a smaller Tafel slope (47 mV dec) than IrO (125 mV dec).

Greenly Synthesized CoPBA@PANI as a Proficient Electrocatalyst for Oxygen Evolution Reaction and Its Green Sustainability Assessments.

Water electrolysis is a key factor to generate mobile and sustainable energy sources for H production. Cobalt-based Prussian Blue analogues encompassed with polymer support electrocatalysts CoPBA@PANI (CoPBA@PANI-100, CoPBA@PANI-200, and CoPBA@PANI-300) have been synthesized and characterized. The well-designed CoPBA@PANI-200/GC shows a low overpotential (η) of 301 mV with a small Tafel slope (56 mV dec), comapred to that of IrO (348 mV ; 98 mV dec) for OER.

Effect of nanoparticle-blended biodiesel mixtures on diesel engine performance, emission, and combustion characteristics.

The research work investigates the combustion, performance, and emission characteristics of a CI engine using neat biodiesel (B100: 100% rubber seed oil methyl ester) mixed with alumina and titanium oxide nanoparticles in the proportions of 25 ppm and 50 ppm separately. Nanoparticles (alumina and titanium dioxide) in different proportions like 25 ppm and 50 ppm were mixed with the neat biodiesel, and 2% of surfactant (Span80) was added, and the mixtures were agitated by an ultrasonicator to achieve uniform particle dispersion in the blend. The nanoparticle-blended biodiesel mixtures are designated as B100A25 (B100 + 25 ppm of alumina), B100A50 (B100 + 50 ppm of alumina), B100T25 (B100 + 25 ppm of TiO), and B100T50 (B100 + 50 ppm of TiO).
