Fullerenes as Key Components for Low‐Dimensional (Photo)electrocatalytic Nanohybrid Materials

Abstract

Recent advances in the area of quantum dots (QDs) have shown their wide range of applications that extend from sensing [50] and bioimaging to catalytic water splitting owing to their remarkable electronic,e lectrochemical, optical, and catalytic properties. [51, 52] Thes ynthesis of QDs can be Alain R. Puente Santiago received his PhD degree in Physical Chemistry with distinction from the University of Cordova, Spain in 2017. He is currently apostdoctoral fellow in Prof. Luis Echegoyen's group in the Chemistry Department of the University of Texas at El Paso. His research interests focus on the developmento flow-dimensional nanohybrids for electrocatalysis. Olivia Fernandez-Delgado was born in Cuba (Havana) in 1993.

Her research interests include the synthesis and characterization of new fullerene and carbon nanoonion derivativesf or photovoltaic, catalytic, and biological applications.

Experimental and Theoretical Advances on Single Atom and Atomic Cluster‐Decorated Low‐Dimensional Platforms towards Superior Electrocatalysts

“…[ 110 ] Additionally, the electron transfer (ET) among nanocarbon supports and metal species represents a significant phenomenon that usually has led to the variation of charge states of the subnanometer metallic clusters, thus influencing the charge density and distribution of metal species, which regulate the electrocatalytic pathways of the overall catalytic reactions. [ 111–113 ] Remarkably, ET processes between tiny metallic clusters and nanocarbon platforms could be controlled by the size of metal particles and the geometry of the metal species in the clusters, thus opening a new avenue towards the rational design of low‐nuclearity electrocatalytic systems that exhibit superior advantages for multifunctional electrocatalysis.

Recent Advancement in Quantum Dot Modified Layered Double Hydroxide towards Photocatalytic, Electrocatalytic, and Photoelectrochemical Applications

“…In comparison to bulk semiconductor materials, semiconductor QDs showcase unique multiexciton properties, suggesting the generation of multiple excitons when a single photon is absorbed. [16,[34][35][36][37] Due to the minute photo electronics transmission distance from the solid to the surface, QDs tiny particle size favors quick charge separation and transmission. For photocatalytic reactions, the distinctive multi-exciton production in QDs can result in high quantum efficiency (even larger than 100 %), impressive specific surface area, and improved light absorption capabilities due to a greater light absorption coefficient act proficiently.…”

Controlling the Interfacial Charge Polarization of MOF-Derived 0D–2D vdW Architectures as a Unique Strategy for Bifunctional Oxygen Electrocatalysis

“…The discovery of efficient energy materials from inexpensive natural sources is currently leading the path toward the development of a sustainable future. − Along with the increasing endeavors to build green energy technologies, the oxygen electrode reactions, including oxygen evolution/reduction, have sparked special attention as crucial steps of renewable energy devices. − Currently, Pt-group metals such as Pt, Ir, or Ru are the state-of-the-art electrocatalysts for oxygen evolution reaction (OER) and oxygen reduction reaction (ORR). , Nonetheless, the high cost and restricted availability of precious metals have significantly blocked their practical applications. As a result, there is an increasing interest to design highly active bifunctional electrocatalysts from earth-abundant materials. − …”
