We provide a comprehensive overview of the recent developments in the field of two-dimensional (2D) materials for energy conversion and storage applications. The focus of this review is the electronic...

Future perspectives in green hydrogen production by catalyzed sono-photolysis of water

“…For the oxygen evolution side, the same process can occur with co-catalysts having the VB placed under the VB of the co-catalysts, promoting the holemigration from photo-to the co-catalyst through the junction interface. In literature, the most employed co-catalysts for the water splitting reaction based on transition metals belong to several families of compounds such as elemental metals, metal sulphides, nitrides, carbides, borides, phosphides, oxides, hydroxides and oxo-hydroxides [36][37][38][39][40][41][42][43][44][45] . The pure solar-tohydrogen process, which is solely based on the use of solar radiation without any external current supply or mediated by electrolyte solutions, is limited by the efficiency, being around 3%.…”

As an example, a recent study reported a target value of about 9% by using concentrated solar irradiation and Ga/In nitride nanoparticles as a co-catalyst.…”

Advances in the Use of Conducting Polymers for Healthcare Monitoring

“…Allotropes and nanomaterials used in combination with and to modify CPs exhibit significant diversity and considerable application potential. They are incorporated in zero-dimensional nanomaterials such as fullerenes [64], quantum dots [65][66][67][68][69], metal and metal oxides [70][71][72]; one-dimensional nanomaterials such as carbon nanotubes [73], silver nanowires [74] and titanium dioxide nanorods [75]; two-dimensional nanomaterial such as boron nitride nanosheets [76], hydrate vanadium dioxide nanosheets [77,78], and graphene [79,80]; and three-dimensional bulk materials such as silicon semiconductors [81], barium titanate filler [82], graphene foam [83], and indium gallium zinc oxide amorphous semiconductors [84]. Consequently, CPs have garnered substantial research interest, with research progressing in two primary directions: improving synthesis methods for the development of CP structures and identifying materials with which CPs can be combined to yield unique properties.…”
