Access to safe drinking water and a hygienic living environment are the basic necessities that encourage healthy living. However, presence of various pollutants (especially toxic heavy metal ions) at high concentrations in renders unfit for domestic use. The heavy-metal ions (e.g., Pb2+, Hg2+, Cr6+, Cd2+, or Cu2+) greater than their permissible limits adversely affects human health, increases risk cancer kidneys, liver, skin, central nervous system. Therefore, detection is crucial. Due benefits "green"-synthesized carbon-dots (C-dots) over other materials, these materials potential candidates sensing sources. C-dots very small carbon-based nanomaterials show chemical stability, magnificent biocompatibility, excitation wavelength-dependent photoluminescence (PL), solubility, simple preparation strategies, photoinduced electron transfer, opportunity functionalization. A new family called "carbon quantum dots" (CQDs) fluorescent zero-dimensional carbon nanoparticles size < 10 nm. green synthesis has numerous advantages conventional routes, such as utilization inexpensive non-poisonous straightforward operations, rapid reactions, renewable precursors. Natural sources, biomass wastes, broadly accepted precursors fabricating because sources economical, ecological, readily/extensively accessible. Two main methods available production: top-down bottom-up. Herein, this review article discusses recent advancements fabrication C-dots: photostability; surface structure functionalization; applications hazardous anions ions; binding with C-dots; probable mechanistic routes PL-based ions. production promising discussed herein provides deep insights into safety health environment. Nonetheless, resource conversion low-value waste valuable (i.e., C-dots) applications.

Abstract Pesticides in environmental samples pose significant risks to ecosystems and human health since they require precise efficient detection methods. Imidacloprid (IMI), a widely used neonicotinoid insecticide, exemplifies these hazards due its potential toxicity. This study addresses the urgent need for improved monitoring of such contaminants by introducing novel fluorometric method detecting IMI using nitrogen‐doped graphite carbon dots (N‐GCDs). The sensor operates quenching fluorescence through interaction Cu 2+ ions with N‐GCDs. Subsequently, binds imidazole group, chelates , restores alternating behavior allows accurate identification both IMI. exhibits linear ranges 20–100 nM 10–140 μg/L IMI, limits 18 1.2 μg/L, respectively. high sensitivity this enables real‐world samples, which underscores practical use agricultural safety.

The exponentially increasing global energy demand along with solid waste, being one of the most omnipresent environmental issues worldwide provides an interesting path to synthesize carbon nanomaterials that exhibit extraordinary properties and applications. As a result these developments, can be used more traditionally as catalysts well in supporting material for fuel cells. One capable cleaner fuels includes They could generate convert extremely efficiently, while harvesting materials resourced. common obstacle applications provided above is they are not backed by cost reduction specifications. In particular there need further research lower-cost electrode Microbial Fuel Cells (MFCs) alternate Proton Exchange Membrane (PEM) solve this problem. Synthesis methods waste-derived CNT materials, namely converting different types wastes like agricultural residues, industrial byproduct municipal waste into highlighted. These offer some inherent advantages such high surface area, unique morphology functional groups make them favourable improving various cell components. This paper will discuss potential application derived from types, proton exchange membrane cells (PEMFCs), alkaline (AFCs) oxide (SOFCs). Their role active oxygen reduction/evolution reaction catalysis status terms reviewes specifically support component electron conductivity stability environmental-sustainability perspective solid-waste-derived nanomaterial synthesis also presented, confirming dual advantage gained management fabrication structured Prospective disputes challenges scaling production commercial level
