Title: Innovations of Hakimu Nsubuga in Electrochemical Systems

Introduction

Hakimu Nsubuga is a notable inventor based in Dhahran, Saudi Arabia. He has made significant contributions to the field of electrochemical systems, particularly in the development of advanced reactor systems for environmental applications. With a total of 6 patents, his work focuses on innovative methods for degrading pharmaceutical contaminants in water.

Latest Patents

Nsubuga's latest patents include a droplet flow-assisted electro-Fenton reactor system. This system utilizes copper-boron-ferrite (Cu—B—Fe) composites that are prepared and immobilized on graphite electrodes using a silica-based sol-gel derived from rice husks. The innovative design allows for the fast in-situ electrogeneration of reactive oxygen species, such as HO and ·OH. By adjusting the bimetallic loading ratios, specifically between 10 to 30 wt. % Fe and 5 to 15% wt. Cu, the catalytic activities for degrading pharmaceutical beta blockers, such as atenolol and propranolol, are significantly enhanced. The system has demonstrated degradation efficiencies of at least 99.9% for both compounds in hospital wastewater. The presence of ·OH radicals indicates a surface mechanism at the inventive cathodes, which benefit from the synergistic contributions of iron and copper. These metals can be embedded in the porous surface of the graphite electrodes, facilitating the conversion of HO to ·OH, thereby improving degradation efficiency. Notably, the inventive cathodes maintain catalytic stability after 20 or more cycles under both neutral and acidic conditions.
