Emerging organic pollutants (EOPs) are serious environmental concerns known for their prominent adverse and hazardous ecological effects, and persistence in nature. Their detrimental impacts have inspired researchers to develop the strategic tools that reduce and overcome the challenges caused by EOPs' rising concentration. As such, biochar becomes as a promising class of biomass-derived functional materials that can be used as low-cost and environmentally-friendly emerging catalysts to remove EOPs. Herein, in-depth synthetic strategies and formation mechanisms of biochar-based nitrogen functionalities during thermochemical conversion are presented. Most prominently, the factors affecting N-surface functionalities in biochar are discussed, emphasizing the most effective N-doping approach, including intrinsic N-doping from biomass feedstock and extrinsic N-doping from exogenous sources. Moreover, biochar-assisted EOPs removal in line with interactions of nitrogen functionalities and contaminants are discussed. The possible reaction mechanisms, i.e., radical and non-radical degradation, physical adsorption, Lewis acid-base interaction, and chemisorption, driven by N-functionalities, are addressed. The unresolved challenges of the potential applications of biochar-mediated functionalities for EOPs removal are emphasized and the outlooks of future research directions are proposed at the end.

Recent trends in advanced oxidation process-based degradation of erythromycin: Pollution status, eco-toxicity and degradation mechanism in aquatic ecosystems Ashraf, Aniqa; Liu, Guijian; Yousaf, Balal; Arif, Muhammad; Ahmed, Rafay; Irshad, Samina; Cheema, Ayesha Imtiyaz; Rashid, Audil; Gulzaman, Humaira (2021-06-01) Wide spread documentation of antibiotic pollution is becoming a threat to aquatic environment. Erythromycin (ERY), a macrolide belonging antibiotic is at the top of this list with its concentrations ranging between ng/L to a few mu g/L in various global waterbodies giving rise to ERY-resistance genes (ERY-RGs) and ERY- resistance bacteria (ERY-RBs) posing serious threat to the aquatic organisms. ERY seems resistant to various conventional water treatments, remained intact and even increased in terms of mass...
Use of conductive polymer-supported oxide-based photocatalysts for efficient VOCs & SVOCs removal in gas/liquid phase Ajmal, Zeeshan; Naciri, Yassine; Ahmad, Munir; Hsini, Abdelghani; Bouzıanı, Asmae; Laabd, Mohmed; Raza, Waseem; Murtaza, Adil; Kumar, Anuj; Ullah, Sami; Al-Sehemi, Abdullah G.; Al-Ghamdi, Ahmed A.; Qadeer, Abdul; Hayat, Asif; Djellabi, Ridha (2023-02-01) Volatile and semi volatile organic compounds (VOCs and SVOCs) are regarding as serious environmental pollutants owign to causing a lot of diseases around the world. The VOCs and SVOCs can be accumulated in both indoor and outdoor areas. Photocatalytic technology has been applied over the last decades in order to purify air and water under solar or artificial lights. To overcome the issues of classical TiO2 photocatalysis, the scientific community has done a lot of research on the engineering of photocatalyt...
Ambient VOC concentrations in the city of Balikesir and its environment Yalçın, Giyasettin Efdal; Tuncel, Süleyman Gürdal; Department of Environmental Engineering (2013) The assessment of volatile organic compounds (VOCs) has become an important field of interest in atmospheric pollution. This study quantifies and characterizes the ambient levels and spatial distribution of VOCs in urban and rural areas of Balıkesir. In addition, for the city drinking water dam excess flux from the traffic estimation was done. For these assessments passive sampling of VOCs performed at approximately 50 locations in and around the city of Balıkesir and analyzed with GC-FID system. Tenax TA w...
Spatial distribution of organic pollutants in Bursa atmosphere : seasonality and health effects Yılmaz Civan, Mihriban; Tuncel, Süleyman Gürdal; Department of Environmental Engineering (2010) The assessment of volatile organic compounds (VOCs) has become an area of particular interest in the field of atmospheric pollution due to their adverse health and environmental effects. This study is aimed to identify, quantify and characterize VOC in different urban areas and industrial areas in Bursa. The spatial distribution, seasonal variation as well as health risks assessment of VOC were discussed. Air samples were collected by means of sorbent passive sampling at over 50 sampling points in Bursa and...
Fabrication of Highly Catalytically Active Gold Nanostructures on Filter-Paper and Their Applications towards Degradation of Environmental Pollutants Khan, Ghazanfar Ali; Nalbant Esentürk, Emren; Bek, Alpan; Bhatti, Arshad Saleem; Ahmed, Waqqar (2021-10-01) Supported metallic nanoparticles (NPs) have recently become a promising candidate for the degradation of environmental pollutants. In this work, we report the fabrication of highly catalytically active, surfactant-free interconnected Au nanostructures directly on filter paper. The width of nanostructures is only a few nanometers and they contain high concentration of low-coordination atoms. Our approach involves the immersion and evaporation of Au precursor solution on the filter paper and its subsequent re...
