Themed collection Water pollution

Electrochemical sensors demonstrate outstanding performance at detecting heavy metal ions, with a high specific surface area and high sensitivity which can excellently complete the on-site detection of trace heavy metal ions in water.

Graphdiyne 2D-nanomaterial having uniform pores structure favor its applications in wastewater remediation. This article provides deep insights into GDY's structure, properties, synthesis methods, and its applications in wastewater treatment.

Recently, bubble-propelled micro/nanomotors have been considered as the cutting-edge micro/nano-sensing tools that use their unique features for fast detection of various hazardous environmental pollutants and biosensing.

Stimuli-responsive polymers are a new category of smart materials used in water treatment via a stimuli-induced purification process and subsequent regeneration processes.

The shortage of freshwater resources caused by heavy metal pollution is an acute global issue, which has a great impact on environmental protection and human health.

We investigate via atomistic simulations the capture of lead ions from water by hemicellulose – as representative of the polysaccharides that are common components of vegetables and fruit peels – and the reverse process.

Medicines and pesticides are being used excessively, misused, or abused in recent times, resulting in major environmental contamination and, more specifically, water pollution.

Water pollution caused by the continuous development of industrialization has always been a common concern of mankind.

Water pollution caused by the frequent use of combined sewer overflows (CSOs) has been attracting increased media and political coverage in England as in other places in the world.

A 3D printed hydrogel-based adsorbent provides an easy, eco-friendly, and cost-effective way to remove heavy metal ions from aqueous environments.

The band structure analysis shows that BWO and MIL-101(Fe) is typical type-II scheme, which provokes that the photogenerated carriers will transfer from a more positive position to a more negative position. The Z-scheme heterojunction is proposed.

A novel type II SnNb₂O₆/MgIn₂S₄ composite photocatalyst was prepared. The prepared composite photocatalyst exhibited significantly improved photocatalytic activity for Cr(VI) reduction and tetracycline hydrochloride degradation under visible light.

Severe impacts of water contamination on the environment and human health have compelled us to study and design an efficient and reusable filter with tunable pore size.

An electroactive and free-standing nanohybrid filter, consisting of single Cu atoms and MXene, enables ultrafast degradation of emerging contaminants.

MoS₂ NFs have exhibited abundant active sites in odd-number layers to piezoelectrically activate PMS for producing ˙OH and SO₄˙⁻ in order to degrade organic pollutants.

Frequent cyanobacterial blooms in eutrophic waters produce a variety of toxins such as microcystins (MCs), which are seriously harmful to waterbodies and human health.
