Accelerating NADH oxidation and hydrogen production with mid-gap states of nitrogen-rich carbon nitride photocatalyst.

Regeneration of electron carriers such as NAD/NADH is highly desirable and essential for enzymatic conversions. Here, we demonstrate a sustainable strategy for the regeneration of NAD as an electron carrier via photon-assisted heterogeneous catalysis. For this, a mid-gap state induced nitrogen-rich polymeric carbon nitride (NPCN) catalyst was synthesized by an additive-assisted thermal copolymerization.

A Novel Synthesized 1D Nanobelt-like Cobalt Phosphate Electrode Material for Excellent Supercapacitor Applications.

In the present report, we synthesized highly porous 1D nanobelt-like cobalt phosphate (CoPO) materials using a hydrothermal method for supercapacitor (SC) applications. The physicochemical and electrochemical properties of the synthesized 1D nanobelt-like CoPO were investigated using X-ray diffraction (XRD), X-ray photoelectron (XPS) spectroscopy, and scanning electron microscopy (SEM). The surface morphology results indicated that the deposition temperatures affected the growth of the 1D nanobelts.

Electrocatalytic oxidation of antidiabetic drug metformin adsorbed on intercalated MXene.

Two-dimensional (2D) TiCT transition metal carbide (MXene) nanosheets intercalated with sodium ions (SI-TiCT MXene) were used in the adsorption and electrochemical regeneration process for removal of the antidiabetic drug metformin (MF) as a model emerging pollutant. After MF adsorption, SI-TiCT MXene oxidized the MF on its surface through its electrocatalytic activity at very low current density and cell potential. For complete oxidation the optimum parameters were 0.

Development of a three-dimensional macroporous sponge biocathode coated with carbon nanotube-MXene composite for high-performance microbial electrosynthesis systems.

Microbial electrosynthesis (MES) is a renewable energy platform capable of reducing the carbon footprint by converting carbon dioxide/bicarbonate to useful chemical commodities. However, the development of feasible electrode structures, inefficient current densities, and the production of unfavorable electrosynthesis products remain a major challenge. To this end, a three-dimensional (3D) macroporous sponge coated with a carbon nanotube/MXene composite (CNT-MXene@Sponge) was evaluated as an MES cathode.

MXene-coated biochar as potential biocathode for improved microbial electrosynthesis system.

Microbial electrosynthesis (MES) holds tremendous large scale energy storage potential. By promoting the bioconversion of carbon dioxide (bicarbonate) into useful chemical commodities, this technique utilizes renewable energy and reduces carbon footprint. However, expensive electrode materials, low current densities, and multiple electrosynthesis products are major challenges to this field.
