Although intensive efforts have been made and great progress has achieved relating to the electrocatalytic hydrogen evolution reaction (HER), an advanced synthesis strategy for efficient electrocatalyst is still most significant goal.

Hybrid nanocomposites of binary Pt-Ru/Polyaniline were prepared by oxidative polymerization of aniline andformation Pt and Ru nanoparticles. The polymerization of aniline was carried out in the presence of Potassiumhexa cyano Platinate (IV) and Ruthenium (III) nitrosyl nitrate as oxidizing agents. During the reaction anilinemonomers undergo oxidation and form polyaniline (PANi) whereas the redu...

The interaction between ionomer (ion-conducting polymer) and catalyst particles in porous electrodes of electrochemical energy-conversion devices is a critical yet poorly understood phenomenon that controls device performance. This interaction stems from the electrode precursor inks, which also governs porous-electrode morphology during formation. In this letter, we probe the origin interaction...

Nitrite contamination of groundwater is a concerning consequence anthropic activity. The electrochemical detection nitrite in water based on direct electrocatalytic oxidation over modified electrodes. However, drawbacks associated to the high potential required, oxide layer formation, and O2 interference are present. Considering recent availability low cost platinum-group-metal-free (PGM-free) ...

We demonstrate Ni–N/C is an effective electrocatalyst for the direct conversion of captured CO 2 in monoethanol amine-based aqueous absorbents showing high faradaic efficiency (78%) and its selectivity maintained various amine solvents.

Pt ions dissolved in artificial seawater were recovered using layered polysilane (LpSi). Hydrosilyl groups (Si–H) LpSi selectively reduced ions, and the resulting 0 loaded catalysed hydrogen evolution reaction as an electrocatalyst.

3-D mesoporous triphasic cobalt–copper phosphides is used as highly efficient bifunctional, stable electrocatalyst for water-alkali electrolyzers. This offers a lower cell voltage when compared to noble-metal-based Pt/C–IrO2/C.
