ZnS microparticles were synthesized into four distinct morphologies: microrods, spherical aggregates, microflakes, and microflowers using the solvothermal method. These morphologies were characterized using XRD, FESEM, EDS analysis, UVVis spectroscopy, XPS, and BET analysis. The tribocatalytic activity was assessed by degrading methylene blue (MB) dye under magnetic stirring in a dark setting. The experiment was carried out at the neutral pH of MB solution (~ 6.5). Among the prepared ZnS morphologies, the micro flakes displayed the largest surface area (120m/g) and exhibited enhanced dye degradation efficacy, achieving 57% MB elimination after 15h of agitation at 800rpm, corresponding to a pseudo-first-order rate constant of 0.054min?. By analyzing the degradation kinetics as pseudo- first-order kinetics, we elucidated the crucial significance of surface morphology and contact area in facilitating effective electron transfer during tribocatalysis. Additionally, we investigated the influence of PTFE bar size, material concentration, stirring speed and initial dye concentration on degradation efficiency. Reusability test demonstrated stable performance over four consecutive cycles with a minor decrease (~ 5%).
