Abstract Limited information is available about potential physicochemical changes that can occur in hydrochar post-production, e.g. during drying and storage. Understanding these crucial not just for shaping future research plans, but also practical applications. Here we studied the effect of moisture (69.2% 2.4%) three storage temperatures (− 18, 4, 20 °C) over a year on selected organic inorganic compounds produced from Hydrothermal carbonization (HTC) digested cow manure. Comparison control wet hydrochars (WHs) dry (DHs) showed compound composition due to drying. Overall, total amount was notably greater WH (15.2 g kg −1 DM) compared DH (11.8 DM), with variations observed individual concentrations. Drying, however, had no significant influence identified compounds. Storage caused both DH, particularly after 12 weeks. Sugars (2–sevenfold), acids (36–371%), aromatics (58–120%) stored samples at week 52 were significantly higher than their values. Changes elements (e.g., Co, K, Mg, Mn, P, S, Sr, Zn) occurred faster WH, differences starting 1 values, while fewer changes. Based content, recommend optimal conditions HTC studies preserve properties. Finally, discussed applications hydrochars, showing stability, especially − 18 °C, making it suitable various Graphical

Abstract Activated carbon (AC) is the most common and economically viable adsorbent for eliminating toxic organic pollutants, particularly dyes, from wastewater. Its widespread adoption due to simplicity affordable production of AC, wherein low-cost agricultural wastes, such as durian skin can be used. Converting into AC presents a promising solution its solid waste management. However, inherent drawbacks non-selectivity, relatively short lifespan laborious replacement recovery processes diminish overall efficacy an adsorbent. To address these challenges, immobilisation metal nanocatalysts silver nanoparticles (AgNPs) one emerging solutions. AgNPs facilitate regeneration adsorption sites by catalysing conversion adsorbed dyes harmless simpler molecules. Nevertheless, on surface challenging pore size formation hard control nanomaterials easily leach out surface. Hence, in this study, we synthesised (DS) immobilised AC-DS Then, used methylene blue (MB) removal studying capability recyclability AC-DS. In synthesis AC-DS, influences reaction temperature, activating agent, acid-washing adsorptive MB were first determined. It was found that 400 °C, KOH presence (50% HNO 3 ) resulted with highest percentage (91.49 ± 2.86%). results three experiments demonstrate exhibited higher after several cycles (up 6 cycles) compared alone, proving benefit We also AgNPs/Citrate@AC-DS better AgNPs/PVP@AC-DS indicating significant type stabilisers study. This study demonstrates more oxygen-containing functional groups (i.e., carboxyl hydroxyl groups) citrate molecules, has greater influence performance their BET area structure. The findings have potential promote serve guideline harnessing advantages nanomaterials, AgNPs, enhance properties environmental applications.
