Summary: This study investigates the corrosion behavior of N80 steel in the presence of supercritical CO2 and H2S environments. The results show that a low H2S pressure increases the corrosion rate of N80 steel, but further increasing the H2S pressure reduces the rate significantly. The variation in corrosion rate depends on changes in cathode process and overall protectiveness of the corrosion product film caused by H2S. Different corrosion product films are formed on the steel surface depending on the H2S pressure. N80 steel experiences uniform corrosion in the presence of FeCO3 or FeS dominated film, but localized corrosion occurs in the presence of FeCO3 and FeS mixed film.

Summary: In this study, eco-friendly functionalized carbon dots (N-CDs) were synthesized using the microwave method. The corrosion inhibition behavior of N-CDs in acidic and saline solutions was systematically investigated, revealing its outstanding inhibitory performance. N-CDs acted as a mixed inhibitor, suppressing the cathode in acidic conditions and primarily inhibiting the anode in saline solutions. The adsorption of N-CDs on the metal surface through physical and chemical adsorption was found to inhibit corrosion, providing new ideas for efficient and environmentally friendly corrosion inhibitors.

Summary: This study evaluates the interaction between silty sand and corrosion product layer in a sweet environment. Corrosion protection is influenced by two factors: the adsorption and embedment of silty sand, and the presence of a corrosion product layer. Silty sand blocks ion transportation and reduces the dissolution of FeCO3, while the corrosion product layer provides the main protection. This effect is more significant when a full coverage FeCO3 layer is present.

Summary: This study found that high E-C rates mainly occur in locations with high flow velocity or strong impacts from sand particles, leading to localized corrosion in the expansion segment. The inhibitor can significantly reduce the E-C rate, but cannot reduce the difference in erosion rates at different locations on the internal surface of the expansion segment.

Summary: The influence of Ca2+ on the growth mechanism of CO2 corrosion products was explored through weight loss, in situ electrochemical measurements, and analysis of corrosion products. The increase in Ca2+ concentration in the solution weakened the crystallinity of the product film, FexCa(1-x)CO(3), gradually transforming it into an amorphous structure. This resulted in reduced protectiveness and an elevated corrosion rate. Higher concentrations of Ca2+ led to unstable growth of FexCa1-_xCO3. At 10000 mg L-1 Ca2+, complex FexCa1_xCO(3) structures with varying Ca content were formed. A linear relation between Ca2+ concentration in the solution and the molar fraction of Ca in the film was also proposed.

Summary: This study investigates the effects of brine salinity and temperature on the CO2 corrosion of low carbon API N80 steel in CO2-saturated brines. The results demonstrate that increasing brine salinity reduces the corrosion rate at lower temperatures, but increases it at higher temperatures. Additionally, the corrosion rate is enhanced with increasing temperature until a certain point, after which it starts to decrease. Quantitative analysis reveals that the synergistic action of salt concentration and temperature has a greater influence on corrosion, with temperature being the most influential parameter.

Summary: The effects of flow rate and particle-wall impact on CO2 corrosion of N80 steel at high temperature were investigated. The results showed that the corrosion product layer formed at 180 degrees C was denser and more protective, leading to a lower corrosion rate compared to that at 90 degrees C. Flow corrosion reduced the formation of polycrystalline layers, while particle-wall impact directly destroyed them. The promotion effect of flow and particle-wall impact on corrosion was significant at 90 degrees C, but weak at 180 degrees C due to faster formation rate of protective layers.

Summary: The synergistic corrosion inhibition for steel in saline solution was achieved by a combination of peach pomace extract (PPE) and 3-Aminopropyltriethoxysilane (APTES), providing over 750 hours of protection. Optimization of the solvent for extracting waste products of peach pomace processing was conducted. The highest efficiencies of APTES, PPE, and the combination inhibitor (PPE/APTES) were 3.34%, 85.41%, and 99.25% at 500 ppm, respectively. The excellent inhibition performance of the combination inhibitor can be attributed to the synergistic effect between PPE and APTES. This study comprehensively characterizes the mechanism of action of PPE and APTES as a combination corrosion inhibitor for saline solution using targeted analyses and commonly used methods such as gravimetric, electrochemical measurement, SEM/EDX, and FTIR. Test results confirm that the combined extract and organosilan control 96-98% of corrosion in the saline solution. Potentiodynamic polarization curves indicate that the combination corrosion inhibitor acts as a mixed-type inhibitor, significantly reducing the corrosion current density from -20 (without inhibitor) to 2.1 mA/cm2 upon addition of the inhibitor. A SWOT analysis was used to evaluate the relevance of adopting the corrosion inhibitor in chemical industry applications.

Summary: In this study, the corrosion rates of natural gas pipeline steel X80 in a H2S/CO2 coexistence environment were investigated under different H2S/CO2 partial pressures, temperatures, and applied stresses. The results showed that the corrosion of X80 steel was more severe under pure CO2 condition than in the presence of H2S. The formation of amorphous Cr (OH)3 improved the corrosion stability of X80 steel in the H2S/CO2 coexistence environment. The corrosion rates of X80 steel increased with the increase of H2S partial pressure and temperature, while the applied stress significantly accelerated the corrosion process.

Summary: Developing efficient and inexpensive electrocatalysts for the hydrogen evolution reaction (HER) is crucial for the commercial viability of electrochemical clean energy technologies. Transition metal phosphides (TMPs) have been recognized as attractive HER catalytic materials due to their abundant reserves, unique structure, tunable composition, and high electronic conductivity. However, the HER activity of TMPs is still limited by various issues and performance bottlenecks. This review addresses these issues, provides explanations and solutions based on the origins of HER catalytic activity in TMPs, presents strategies to improve HER performance, and proposes critical scientific issues for constructing high-efficiency TMP-based electrocatalysts. Challenges and future directions for this research field, including the HER reaction process, catalytic mechanism research, TMP-based catalyst construction, and application expansion, are also discussed.

Summary: The synthesis of three-dimensional interconnected honeycomb-like carbon nanosheets (RTK-3) using homemade phenolic resin, KOH etching, and in situ doping of thiourea resulted in nanosheets with a large surface area (2277.71 m(2) g(-1)) and rich in heteroatoms. This led to outstanding electrochemical performance, with specific capacitances of 349 F g(-1) at 0.5 A g(-1) and 217 F g(-1) at 10 A g(-1). Additionally, the assembled symmetric supercapacitor (RTK-3//RTK-3) showed exceptional performance in different aqueous electrolytes, with energy density of 6.11 W h kg(-1) at a power density of 249.61 W kg(-1) in alkaline electrolytes and a preeminent energy density of 36.34 W h kg(-1) at 810.11 W kg(-1) in neutral electrolytes due to its larger potential window (0-1.8 V). The utilization of resin-based carbon materials to prepare high-performance supercapacitors represents a novel approach and could potentially lead to the application of other large surface area and heteroatom-doped materials in energy storage.
