Highly Efficient Photothermal Reduction of CO on PdCu Dispersed TiO Photocatalyst and Operando DRIFT Spectroscopic Analysis of Reactive Intermediates.

The photocatalytic conversion of CO to fuels using solar energy presents meaningful potential in the mitigation of global warming, solar energy conversion, and fuel production. Photothermal catalysis is one promising approach to convert chemically inert CO into value-added chemicals. Herein, we report the selective hydrogenation of CO to ethanol by PdCu alloy dispersed TiO (P25) photocatalyst.

Operando Investigation of Structural and Chemical Origin of CoO Stability in Acid under Oxygen Evolution Reaction.

Replacement of an expensive anode electrocatalyst in proton exchange membrane water electrolysis is of great importance. Recently explored CoO shows good activity and stability toward oxygen evolution reaction (OER) in acid; however, the stability is not adequately explained. Lack of such information delays the design of an acid-stable OER electrocatalyst.

Studies on the sonochemical polymorphism of SbO on activated graphite for the electrochemical determination of imipramine.

This work reports the simultaneous sonochemical activation of graphite and sonohydrolysis of antimony chloride (SbCl) in the alkaline medium. The experiments conducted by bath sonicator operated at 37 kHz of frequency and a maximum power of 150 W. The simple sonohydrolysis of SbCl alone produced an orthorhombic phase of SbO, whereas, it produced mixed phases of cubic and orthorhombic SbO when introduced with graphite.

Effect of cavitation erosion in the sonochemical exfoliation of activated graphite for electrocatalysis of acebutolol.

This study mainly covered the cavitation erosion in probe sonication and its electrochemical behavior. The activated graphite was exfoliated by the probe sonication wherein the titanium alloy (TA) is used as a probe (micro-tip). The sonication performed in the aqueous solution contains a mixture of sulfuric acid and nitric acid (1:1).
