Iron (Fe)- and nitrogen (N)-codoped carbon materials hold broad application prospects in the oxygen reduction reaction (ORR) because of their abundant reserves, low cost, excellent catalytic activity. In this study, a N-doped nanotube (CNT)–graphene framework with encapsulated Fe/Fe3N nanoparticles (Fe–N–CNT@RGO) is designed synthesized by annealing mixture iron acetylacetonate, dicyandiamide, graphene oxide via one-step calcination strategy. Fe–N–CNT@RGO has better ORR activity than reduced...
This study systematically investigated three influential factors—water-to-binder ratio, cement/sand and steel fiber content—that significantly impact the performance of ultra-high-performance concrete (UHPC). Utilizing Response Surface Methodology (RSM) with a Central Composite Design (CCD), 20 carefully designed mix proportions underwent comprehensive experimental testing. Through rigorous statistical analysis, models were established to elucidate complex relationships between specified...
Surrounding rock pressure is a crucial parameter in tunnel engineering design, and its calculation classic challenge. The surrounding influenced by geostress, but existing methods often do not take into account the effect of geostress. In this paper, finite discrete element method (FDEM) used to study design values under different geostress fields. Firstly, set calibration for input parameters FDEM summarized based on previous studies. Then, taking high-speed railway IV-level as an example,...
The homogeneous dispersion of graphene oxide (GO) in cementitious materials is critical to achieve the unique properties this mixture. In study, based on formation kinetic GO aggregation and production procedure cement, an isolated-dispersion strategy isolating by cement particles has been successfully developed. cross-linking behavior between adjacent sheets inhibited during hydration process, which achieved ball milling process grinding clinker, gypsum, a planetary mill. hardened paste...
Abstract Background Graphene oxide (GO) has abundant oxygen‐containing functionalities such as hydroxyl groups and carboxyl with distinct acidities. This feature makes GO a potential solid acid catalyst for the acid‐catalyzed reactions production of ethyl levulinate (EL), platform chemical, from acid‐treatment furfuryl alcohol (FA). The structure are closely related to its catalytic performance, thus it is necessary establish relationship between chemical properties GO. To achieve this aim,...
