“…Li et al prepared a composite film of carbon black nanoparticles and sulfonated-polythiophene (CB-NPs/s-PT) on a flexible titanium foil and used it as the CE of DSSCs. 569 The CB-NPs provided a large number of catalytic active sites and the s-PT as a conductive binder improved the inter-particle linkage and adhesion. The flexible CB-NPs/s-PT composite film possessed good catalytic ability and rapid reduction kinetic rate constant of I 3…”

Dye-sensitized solar cells (DSSCs) are regarded as prospective solar cells for the next generation of photovoltaic technologies and have become research hotspots in the PV field. The counter electrode, as a crucial component of DSSCs, collects electrons from the external circuit and catalyzes the redox reduction in the electrolyte, which has a significant influence on the photovoltaic performance, long-term stability and cost of the devices. Solar cells, dye-sensitized solar cells, as well as the structure, principle, preparation and characterization of counter electrodes are mentioned in the introduction section. The next six sections discuss the counter electrodes based on transparency and flexibility, metals and alloys, carbon materials, conductive polymers, transition metal compounds, and hybrids, respectively. The special features and performance, advantages and disadvantages, preparation, characterization, mechanisms, important events and development histories of various counter electrodes are presented. In the eighth section, the development of counter electrodes is summarized with an outlook. This article panoramically reviews the counter electrodes in DSSCs, which is of great significance for enhancing the development levels of DSSCs and other photoelectrochemical devices.

“…Then, 5.0 L of 0.4 mmol L −1 thionine aqueous solution was added on the CB-SPE surface, which was used as the electron mediator specie. Next, the laccase enzyme was supported on the previous modified surface using 5.0 L of a laccase solution prepared with optimized enzyme units (1.19 U). Finally, the biosensor surface was mechanically protected using a Nafion5 coating.…”

“…Talarico et al [53] proposed a biosensor based on inhibition of acetylcholinesterase (AChE) enzyme for the determination of different organophosphate and carbamate pesticides. A GCE surface was modified in a first step with a CB and pillar [5] arene as electron mediator, followed by the AChE enzyme using carbodiimide as linkage. Under the optimized experimental conditions, wide linear concentration ranges and very low detectability levels were obtained for the chronoamperometric identification of aldicarb, carbofuran, malaoxon, and methyl-paraoxon, as can be seen from data shown in Table 3.…”

Carbon black (CB) is a nanostructured material widely used in several industrial processes. This nanomaterial features a set of remarkable properties including high surface area, high thermal and electrical conductivity, and very low cost. Several studies have explored the applicability of CB in electrochemical fields. Recent data showed that modified electrodes based on CB present fast charge transfer and high electroactive surface area, comparable to carbon nanotubes and graphene. These characteristics make CB a promising candidate for the design of electrochemical sensors and biosensors. In this review, we highlight recent advances in the use of CB as a template for biosensing. As will be seen, we discuss the main biosensing strategies adopted for enzymatic catalysis for several target analytes, such as glucose, hydrogen peroxide, and environmental contaminants. Recent applications of CB on DNA-based biosensors are also described. Finally, future challenges and trends of CB use in bioanalytical chemistry are discussed.

Carbon derived from hair is interesting because it has good electrocatalytic activity due to the existence of innate heteroatom dopants especially nitrogen and sulfur. In this study, a carbon catalyst containing high nitrogen contents (9.47 at.%) was fabricated without using any harsh chemicals. Moreover, the carbonization temperature was only 700°C. Carbonized hair/ PEDOT:PSS composites (C x P) with varied carbon contents from x = 0.2 to 0.8 g were tested as a counter electrode (CE) for a dye-sensitized solar cell (DSSC). This type of DSSC CE has scarcely been investigated. A DSSC with a C 0.6 P CE provides the best efficiency (6.54 ± 0.11%) among all composite CEs because it has a high fill factor (FF) and a high short-circuit current density (J sc ). The efficiency of DSSC with C 0.6 P CE is lower than Pt's (7.29 ± 0.01%) since the Pt-based DSSC has higher FF and J sc values. However, C 0.6 P is still promising as a DSSC CE since it is more cost-effective than Pt.
