Pore size modulation of cobalt-corrole-based porous organic polymers for boosted electrocatalytic oxygen reduction reaction

Materials Today Catalysis, Journal Year: 2024, Volume and Issue: 5, P. 100050 - 100050

Published: April 21, 2024

The highly active and selective oxygen reduction reaction (ORR) is vital to promote the performance of advanced energy conversion systems, such as fuel cells other electrochemical devices. Porous framework materials have capability combine catalytic units with their porous characteristics, making them promising catalysts. However, due difficulty in designing synthesizing units, pore size modulation primarily achieved by altering linkers. We herein report design synthesis three cobalt-corrole-based organic polymers (Co-POP-1, Co-POP-2 Co-POP-3) different sizes, which were obtained extending 5,15-meso substituents Co corroles. Compared Co-POP-1 Co-POP-2, Co-POP-3 has largest size. Benefiting from enhanced mass transfer exposed sites, displayed remarkably boosted activity for four-electron/four-proton (4e−/4H+) ORR a half-wave potential E1/2 = 0.89 V versus reversible hydrogen electrode (RHE) 0.1 M KOH solutions. This work not only presents polymer catalyst high selectivity but also provides new strategy moderate materials.

Milestones and Most Recent Advances in Corrole’s Science and Technology

Journal of the American Chemical Society, Journal Year: 2023, Volume and Issue: 145(23), P. 12429 - 12445

Published: May 31, 2023

The renaissance in corrole chemistry is strongly correlated with synthetic breakthroughs that started 1999, regarding the one-pot rather than multistep syntheses of this heme-like N4 macrocycle. This largely improved accessibility allowed for technological advances wherein corresponding metal complexes have since been introduced as key elements. Great emphasis was devoted to elucidation unique fundamental features distinguish ligands, among them outstanding electron donation (σ by N atoms and π macrocycle) transition metals chelated them. Such investigations remain crucial enabling by-demand tuning metallocorrole properties distinctly different applications. These range from catalysis organic reactions, through bioimaging disease prevention/treatment strategies, photo- electrocatalysis clean energy. Surveyed are original reports impacted these developments, together some most recent advances.

Tuberculosis (TB) is among the more frequent causes of death in many countries. For pulmonary TB, early diagnosis greatly increases efficiency therapies. Although highly sensitive tests based on nucleic acid amplification (NAATs) and loop-mediated isothermal (TB-LAMP) are available, smear microscopy still most widespread diagnostics method low–middle-income countries, true positive rate lower than 65%. Thus, there a need to increase performance low-cost diagnosis. years, use sensors analyze exhaled volatile organic compounds (VOCs) has been proposed as promising alternative for several diseases, including tuberculosis. In this paper, diagnostic properties an electronic nose (EN) sensor technology previously used identify tuberculosis have tested on-field Cameroon hospital. The EN analyzed breath cohort subjects TB patients (46), healthy controls (38), suspects (16). Machine learning analysis array data allows identification group with respect 88% accuracy, 90.8% sensitivity, 85.7% specificity, 0.88 AUC. model trained maintains its when it applied symptomatic negative TB-LAMP.
