“…This material was used to determine toxic heavy metals with a detection limit in the nanomolar range. Researchers have also reported that BAC specimens derived from kelp, [90] almond shell, [91] and palm shell [92] possess enhanced surface area and porosity, ultimately providing better sensing performance for the determination of trace metals. Hammani et al [93] have shown that the incorporation of Al 2 O 3 into BAC leads to the formation of a better electrocatalyst for electrochemical sensing.…”

Activated carbon (AC), which has attracted considerable attention as an electrode material, holds much promise for electroanalysis. The unique physical and chemical properties of AC, such as the high surface area, good thermal and electrical conductivity, good anti-causticity, high stability, and low cost make it an electrode material which can generate large profits from a commercialization perspective. Number of biomassderived ACs (BACs) with a variety of pore sizes, porosity, morphology, and crystallinity have been prepared from a range of sources of biomass, including agro-wastes on a large scale. BACs exhibit unique and tunable electrochemical properties depending on their physicochemical properties and thus, have found number of applications in industries, pharmaceutical industry, and water treatment plants. From an electrochemical perspective, researchers have demonstrated the impact of BAC as an electrode material for detecting electroactive drugs, environmental pollutants, and developing electrochemical biosensors. Hence, this paper thoroughly reviews and summarizes the literature published within the last ten years, focusing specifically on the types of analytes detected and electrochemical techniques employed and evaluating their performance (in terms of sensitivity, selectivity, and dynamic ranges) and feasibility for electroanalysis. In addition, the review outlines some constructive advice and scope for further research.

“…More recently, activated carbons and biochars (carbon-rich products formed by the thermal decomposition of biomass) have been employed for the modification of chemical sensors in view of their reduced environmental footprint, low-cost and the combination of different physico-chemical properties. 42,59 In this regard, it was reported that several examples of electroanalytical devices constructed with activated carbons, from different carbon sources, show good performances for the detection of biomolecules, 60–64 pharmaceuticals, 65,66 pesticides, 67,68 and metals 69–71 (Table 1). Some selected recent reports are briefly described hereafter.…”

“…For example, the macropores and mesopores enhance the diffusion of the electrochemical species into the nanopores; the adsorption sites are increased, facilitating excellent physical and chemical adsorption of metal ions; and the reaction kinetics is improved due to the small diffusion length in the 3D porous structure [ 25 , 26 , 27 ]. Previously, hierarchical nanoporous carbon electrodes fabricated by eco-friendly methods using biomass were developed to improve the heavy metal adsorption [ 25 , 26 , 28 ]. The biomass-induced nanoporous electrode-based heavy metal sensor allowed the sensitive detection of heavy metal ions at low concentrations.…”

This article presents the development of a highly sensitive electrochemical heavy metal sensor based on hierarchical porous carbon electrodes with sponge-like edge structures. Micrometer-scale hierarchical nanoporous carbon electrodes were fabricated at a wafer-scale using cost-effective batch microfabrication technologies, including the carbon microelectromechanical systems technology and oxygen plasma etching. The sponge-like hierarchical porous structure and sub-micrometer edges of the nanoporous carbon electrodes facilitate fast electron transfer rate and large active sites, leading to the efficient formation of dense heavy metal alloy particles of small sizes during the preconcentration step. This enhanced the peak current response during the square wave anodic stripping voltammetry, enabling the detection of Cd(II) and Pb(II) at concentrations as low as 0.41 and 0.7 μg L−1, respectively, with high sensitivity per unit sensing area (Cd: 109.45 nA μg−1 L mm−2, Pb: 100.37 nA μg−1 L mm−2).
