Distribution and toxicity of dihydroxybenzenes in drinking water sources in Nigeria

“…While there is a permissible limit of 2% for HQ in cosmetics, 14 nothing is said about its permissible limit in water despite the level of its toxicity as previously described. The focus is rather on the removal of HQ and CAT from water using techniques such as electrochemical, [15][16][17][18] activated carbon electrode [19][20][21][22] as well as the use of adsorption, 23 membrane ltration, 24 and biodegradation. 25 There is therefore, a huge scarcity of information on the distribution and potential health risk assessment of HQ and CAT in environmental matrices like in water bodies globally, and particularly, in Nigeria.…”

Modified electrodes: Utilizing Cu‐modified graphene oxide nanosheets as a cathode in electro‐oxidation synthesis of mild Suzuki–Miyaura cross‐coupling reaction under green and sustainable conditions

“…Whether it involves depositing noble metals like gold (Au), 19 silver (Ag), 20 or platinum (Pt), 21 or integrating transition metals like iron (Fe) 22,23 and nickel (Ni), 24 metal-modified GO nanosheets have become a versatile platform for tailored materials with outstanding performance characteristics in cutting-edge technologies. [25][26][27] Among these innovations, the modification of GO nanosheets with copper (Cu) has emerged as an especially promising approach for catalytic applications. The combination of Cu, a renowned catalytic metal, with GO, a two-dimensional nanomaterial known for its exceptional properties, has unlocked new opportunities in catalysis, ranging from environmental remediation to organic synthesis.…”

“…Metal‐modified GO composites influence the synergistic effects between metal nanoparticles and the GO matrix, resulting in enhanced electrical conductivity, 18 mechanical strength, and surface reactivity as catalysts. Whether it involves depositing noble metals like gold (Au), 19 silver (Ag), 20 or platinum (Pt), 21 or integrating transition metals like iron (Fe) 22,23 and nickel (Ni), 24 metal‐modified GO nanosheets have become a versatile platform for tailored materials with outstanding performance characteristics in cutting‐edge technologies 25–27 . Among these innovations, the modification of GO nanosheets with copper (Cu) has emerged as an especially promising approach for catalytic applications.…”
