Atomic layer deposition created a new coating for platinum catalysts. This coating improves selectivity for hydrogen peroxide (H2O2) detection by blocking interfering substances.
Area of Science:
- Electrochemistry
- Materials Science
- Nanotechnology
Background:
- Platinum (Pt) catalysts are crucial in electrochemical sensing.
- Developing selective electrocatalysts is essential for accurate detection of specific analytes.
- Interferents can compromise the accuracy of electrochemical measurements.
Purpose of the Study:
- To develop highly selective electrocatalysts for hydrogen peroxide (H2O2) detection.
- To enhance the interference resistance of Pt-based electrocatalysts.
- To investigate the use of atomic layer deposition for catalyst modification.
Main Methods:
- Atomic layer deposition (ALD) was employed to coat Pt catalysts.
- A permselective amorphous oxide coating was synthesized.
- The modified catalysts were characterized for their electrochemical properties.
Main Results:
- The ALD-coated Pt catalysts exhibited high selectivity for H2O2.

Alkynes to Aldehydes and Ketones: Hydroboration-Oxidation
One of the convenient methods for the preparation of aldehydes and ketones is via hydration of alkynes. Hydroboration-oxidation of alkynes is an indirect hydration reaction in which an alkyne is treated with borane followed by oxidation with alkaline peroxide to form an enol that rapidly converts into an aldehyde or a ketone. Terminal alkynes form aldehydes, whereas internal alkynes give ketones as the final product.
