“…Such cooperation usually involves a close cooperative relationship, which requires deep integration and collaborative innovation in technology, resources, and talent [20,21]. Many forms of technological innovation cooperation exist, including industry-university-research cooperation, enterprise-enterprise cooperation, and enterprise-research institution cooperation [22][23][24]. Based on common goals and interests, stakeholders work together to address technological challenges through complementary advantages and resource sharing.…”

Due to the dynamic and complex nature of mega construction projects (MCPs), mega construction project risks (MCPRs) have significantly increased in recent years. Technological innovation cooperation (TIC) is accepted as an approach to solve these issues. However, considering the new technological innovation challenges, technological innovation risks (TIRs) have been identified as a limitation of TIC. This study aims to develop a conceptual framework to explain TIC for MCPs. It is based on a review of the literature, engineering practice, and logical reasoning. The conceptual framework describes the interaction between MCPRs and TIC. It points out that MCPRs drive technological innovation, and technological innovation objectives guide the TIC. TIC has a negative effect on solving TIRs, and TIRs positively affect MCPRs. Cooperation performance will mediate the relationship between TIC and MCPRs. The conceptual framework may provide a theoretical basis to guide future empirical studies that validate the relationship between MCPRs and TIC and puts forward reasonable suggestions for MCPs.

“…Currently, CFA is used mainly as building material in the cement and concrete sectors and as soil stabilization for roads, embankments and ash dyke raising, landfill liners or covers, in mine filling, in bricks, blocks and tiles, agriculture, and others [ 6 , 7 , 8 ]. However, these applications reduce solid waste but do not fully exploit the potential uses of this rich resource [ 9 , 10 ].…”

The article presents studies of the influence of parameters of synthesis modes and alkali concentration on the synthesis of zeolite materials from coal fly ash (CFA). The purpose of the study was to synthesise zeolite materials from CFA using the method of alkaline fusion and to determine the susceptibility of selected heavy-metal ions to removal from solutions in an ion exchange process on a selected mesoporous zeolite. It was found that the crystalline phase of sodalite was dominated in all of the samples synthesized. The specific surface area (SBET) of the samples was evaluated using the standard Brunauer–Emmett–Teller (BET) method using N2 sorption. Crystalline zeolite materials have been used to study the efficiency of removing heavy metals from aqueous solutions of Ni2+, Cd2+ and Pb2+. The adsorption data were analyzed using the Langmuir and Freundlich isotherm model. When comparing the estimated coefficient of determination (r2), it was noticed that the sorption data are more accurately described by the Langmuir isotherm and the pseudo-second-order kinetic model. The results of metal adsorption experiments suggest that the synthesized zeolite material has great potential to be used as an inexpensive and alternative source in the production of adsorbents.

“…As the primary solid waste generated by thermal power plants, CFA is released along with the flue gas during the combustion of coal, potentially contributing to the formation of haze [1,2]. Currently, global CFA emissions are substantial, with China and India together accounting for approximately half of the global emissions [3,4].…”

Coal fly ash (CFA) is the primary solid waste generated by the coal-fired industry, and the predominant treatment methods include accumulation, landfill, and the production of cement-based building materials. However, the availability of these methods is relatively limited, and there is a need for technological upgrades. The extensive accumulation not only leads to environmental pollution but also has detrimental effects on human health. With its loose structure and main chemical components of Al2O3 and SiO2, CFA is conducive to the synthesis of promising nanoporous materials for applications in adsorption. The use of CFA as a raw material can significantly reduce preparation costs, improve comprehensive utilization efficiency, and manufacture more valuable products, aligning with the current strategy of sustainable development. Currently, the most widely used synthesis method is hydrothermal synthesis. This review focuses on the principles, methods, and influencing factors of synthesis, with particular emphasis on CFA-based mesoporous silica, zeolites, and metal–organic frameworks (MOFs), which have not been systematically reviewed previously. The quality of these synthesized nanoporous materials can be finely adjusted through the synthesis process. A comparison of the advantages and disadvantages of each process will be made, and the impact of the synthesis conditions on the synthetic products will be analyzed. Additionally, a brief discussion on the latest research advances in their applications in adsorption will be provided. Finally, relevant challenges and issues have been proposed.
