Are green HRM Practices enough to build successful green ventures interlinked with innovation and knowledge-sharing behavior? Case of China

Green practices are now treated as an essential component of organizational element and firms are now exploring ways to incorporate new growth strategies that ensure environmentally friendly methods. The present study focuses on manufacturing industry in China and identify that green HRM practices influence eco-innovation and organization's knowledge-sharing culture. The study also aims to identify whether eco-innovation and knowledge-sharing culture help to build successful green venture and provide indirect path to green HRM and green ventures. An adopted survey was used to collect data from manufacturing employees and SPSS-AMOS is employed to assess the model reliability and proposed hypotheses. Study outcomes reveal that green HRM practices increase knowledge-sharing behavior and promote green innovation. Findings also expose that eco-innovation and knowledge-sharing behavior are potential mediator, hence provide an indirect path between green HRM practices and green ventures. Results confirm that essentiality of green HRM in order to promote knowledge-sharing behavior among employees through which environmental commitment can be fulfilled by organizations, further leading to successful green venture.

Preparation of Ti/SnO2-Sb/La-βPbO2 electrode and its application in the degradation of some pollutants including prednisolone and 8-Hydroxyquinoline

In this work, a novel La-doped βPbO₂ (Ti/SnO₂-Sb/La-βPbO₂) was prepared using electrodeposition method and applied to the degradation of prednisolone (PRD), 8-Hydroxyquinoline (8-HQ), and other typical organic pollutants. Compared with the conventional electrode Ti/SnO₂-Sb/βPbO₂, La₂O₃ doping enhanced oxygen evolution potential (OEP), reactive surface area, stability and repeatability of the electrode. The 10 g L^-1 of La₂O₃ doping exhibited the highest electrochemical oxidation capability of the electrode with [•OH]ss being determined at 5.6 × 10^-13 M. The quenching experiments were conducted to confirm the main oxidizing species (here: •OH) in the electrochemical process. The study showed that the pollutants were removed in the electrochemical (EC) process with different degradation rates and indicated that the second-order rate constant of organic pollutants towards •OH (k_OP,•OH) has a linear relationship with the degradation rate of organic pollutants (k_OP) in the electrochemical process. Another new finding in this work is that a regression line of k_OP,•OH and k_OP can be used to estimate k_OP,•OH of an organic chemical, which cannot be determined using the competition method. k_PRD,•OH and k_8-HQ,•OH were determined to be 7.4 × 10⁹ M^-1 s^-1 and (4.6-5.5) × 10⁹ M^-1 s^-1, respectively. Compared with conventional supporting electrolyte (like SO₄^2-), H₂PO₄^- and HPO₄^2- improved k_PRD and k_8-HQ by 1.3-1.6-fold, while SO₃^2- and HCO₃^- inhibited k_PRD and k_8-HQ significantly, down to 80%. Additionally, the degradation pathway of 8-HQ was proposed based on the detection of intermediates from GC-MS.

Electrochemical degradation of indigo carmine, P-nitrosodimethylaniline and clothianidin on a fabricated Ti/SnO2-Sb/Co-βPbO2 electrode: Roles of radicals, water matrices effects and performance

In this study, the kinetic degradation of several typical organic pollutants was performed on a synthetic electrode (Ti/SnO₂-Sb/Co-βPbO₂). The surface structure and the electrochemical properties of the prepared electrode were investigated, confirming the successful preparation of the electrode using an electrochemical deposition method. The outer layer (Co-βPbO₂) played an important role in reducing the resistance of the electrode and improving its degradation efficiency. The results showed that indigo carmine (IC), p-nitrosodimethylaniline (RNO), and clothianidin (CLO) were effectively degraded within 20 min of electrolysis. Their degradation in the electrochemical process followed the first-order kinetic model with the degradation rate constant of IC being higher than that of RNO and CLO. This was proved by the difference in the reactivity of the target pollutants toward oxidizing radicals (i.e., •OH, SO₄^•-, and Cl•). Their second-order rate constant towards radicals were in the range of 10⁹ - 10¹⁰ M^-1 s^-1 with the highest value being that for IC: k_·OH,IC = 15.1 × 10⁹ M^-1 s^-1 and [Formula: see text]  = 7.4 × 10⁹ M^-1 s^-1. The study calculated the contribution of some oxidizing species, including direct electron transfer (DET), •OH, SO₄^•-, and other reactive oxygen species (ROS). Solution pH, supporting electrolyte, and water matrix affected the degradation efficiency of pollutants and the contribution of the oxidizing species. Br^- and I^- ions enhanced the degradation rate of organic pollutants, while Fe²⁺, HCO₃^-, and humic acid (HA) reduced it. In addition, the toxicity, total organic carbon (TOC) removal, mineralization current efficiency (MCE), energy consumption, recyclability and stability of the prepared electrode were studied, suggesting that the prepared Ti/SnO₂-Sb/Co-βPbO₂ is a good candidate for treating organic pollutants using the electrochemical oxidation process.
