Two-Fold Interpenetrated Binuclear Nickel Metal–Organic Framework as a Heterogeneous Catalyst for N-Heterocycle Synthesis

“…The peak of [Ni 2 (btb)(DMF)(EtOH)H] 2+ ( m / z 335.5) has the biggest relative abundance, which is similar to the formula of the Nibtb ’s framework ([Ni 2 (btb) 1.333 (H 2 O) 3.578 (py) 1.422 ]). This result indicates that the coordination framework of nickel has a certain stability and integrity even if the framework of Nibtb is destroyed and may further prove the stability of the coordination environment of Ni catalytic sites under heterogeneous catalytic conditions. , Additionally, the catalytic efficiency in the seventh cycle did not decrease significantly (Figure d). The hot filtration experiment proves the heterogeneous nature of this catalytic system (Figure S6).…”

Refractive Index of Single Surface Nanobubbles

“…Bubbles play critical roles in various gas evolution processes, including boiling, 1,2 biomedical ultrasound imaging, 3 catalytic water splitting, 4 and gas storage. 5 In order to understand this general and fundamental gas state in liquid, great efforts have been made. On the basis of the diffusion equation and Laplace pressure, the classical Epstein−Plesset theory 6 successfully explained the behaviors of microsized bubbles.…”

Metal–organic framework-loaded carbon-encapsulated nano-catalyst as a pH-universal oxygen reduction reaction electrocatalyst for various fuel cell devices

“…22 Researchers have studied that the cathodic ORR rate is slower than that of the anode reaction rate in fuel cells. [23][24][25] So far, Pt-based materials have usually been utilized to expedite electrocatalysts for the ORR owing to their reduced oxygen intermediate adsorption Gibbs free energy (ΔGO*). 26 However, the scarcity of resources and high cost make their application severely hampered.…”
