These advantages endow fullerene with a great number of derivates and composites. Many theoretical and experimental works are reported on electrocatalysts. To better understand the study progress, herein, we give a common review of the latest research. We first introduce the theoretical calculations of fullerenes and their derivates towards ORR, OER, and HER, aiming to give understandable reaction mechanisms and electrocatalytic active sites. Then, the experimental identification of the electrocatalytic performance was summarized. The experimental section is organized based on fullerene-based composites including fullerene/carbon composites, fullerene/sulfide composites, fullerene/LDH or metal composites, and fullerene molecular and its derivates including fullerene crystals, fullertubes, as well as endohedral fullerene. Finally, the challenges and opportunities for rational designing of electrocatalysts using fullerene as a precursor or additive are summarized and highlighted. The review not only points out the recent progress in fullerene application in electrocatalysts but also gives an in-depth insight into the materials design theoretically and experimentally that helps the future study directions.</p></div>","PeriodicalId":100036,"journal":{"name":"Advanced Sensor and Energy Materials","volume":"2 2","pages":"Article 100061"},"PeriodicalIF":0.0,"publicationDate":"2023-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49715679","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This review presents the application of nanomaterials for qualitative and quantitative electrocatalytic analysis of drugs of abuse, mostly opioids (such as heroin (HER), morphine (MOR), codeine (COD), fentanyl (FEN), and tramadol (TR)), and addictive stimulants (such as cocaine (COC) and methamphetamine (MAM)) <em>via</em> direct oxidation. Electroanalytical techniques have attracted attention for generating point-of-use sensors because of their low cost, portability, ease of use, and the possibility of miniaturization. Electroanalytical-based devices can assist first responders with tools to identify unknown powders and to treat victims of drug abuse. Based on the drug therapeutic and usage purposes, research advances in drug electroanalysis can be classified and discussed with special emphasis on the electrochemical reaction mechanism of the drug.

Here, a novel tetraphenylethylene (TPE)-doped covalent organic frameworks (TPE-COFs) with strong aggregation-induced electrochemiluminescence (AIECL) response was synthesized and introduced to construct an ultrasensitive biosensor for the detection of miRNA-21. The strong aggregation-induced emission (AIE) response was obtained because the molecular motion of TPE was restricted by COFs which had the porosity and highly ordered topological structure. Meanwhile, the porous structure of COFs allowed TPE to react with electrochemiluminescence (ECL) coreactants more effectively. Furthermore, COFs significantly improved the electron transport efficiency of the entire ECL system. All of these endowed the TPE-COFs with superior AIECL performance. Then, a TPE-COFs based ECL resonance energy transfer (ECL-RET) system was constructed for ultrasensitive miRNA-21 biosensing with differential signal readout. The proposed assays exhibited excellent sensitivity with a wide dynamic range from 10 aM to 1 pM and a low detection limit of 2.18 aM. Therefore, these indicated that doping TPE in COFs was a creative way to develop functional COFs and provided an effective way for enhancing AIECL.

Unfortunately, the sluggish kinetics of oxygen reduction reaction (ORR) on the cathode leads to considerable overpotential and thus severely lowering its operational energy conversion efficiency. Although Pt-based catalysts have been developed as the most efficient catalyst towards ORR, however, their stability is far from the application requirements, which hinders the large-scale application of PEMFCs to a certain extent. Thus, improving the stability of Pt-based catalysts is urgently desirable to advance the widespread commercialization of fuel cells. This review focuses on the stability of Pt-based ORR catalysts in PEMFCs, from the perspectives of catalyst degradation mechanism and stability improvement strategies. It is aimed at providing research directions for the development of stable Pt-based catalysts. Firstly, degradation of metal nanoparticles (dissolution, migration, agglomeration, Ostwald ripening, etc.) and corrosion of carbon supports are introduced. To conquer the two attenuation mechanisms, stability improvement strategies such as constructing intermetallic compounds, enhancing metal-support interaction and the modification of carbon support, are summarized in detail. In addition, some typical stability characterization techniques are outlined. Finally, we discuss the challenges and possible research directions in the future. We hope this review can help readers gain insights into the stability issues of Pt-based ORR nanocatalysts and encourage research that will enable the commercialization of PEMFCs.</p></div>","PeriodicalId":100036,"journal":{"name":"Advanced Sensor and Energy Materials","volume":"2 2","pages":"Article 100058"},"PeriodicalIF":0.0,"publicationDate":"2023-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49732361","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This emitted light is then trapped inside the LSC by total internal reflection, and it travels to the edges of the plate where it is collected by photovoltaic (PV) solar cells (SCs). The use of PRV materials in LSCs offers several advantages over other materials. PRV materials are highly efficient at converting light into electricity.
