Emerging Directions in Bioelectrochemistry, Electrocatalysis and Intelligent Electrochemical Characterisation

This special issue belongs to the section “Chemical and Molecular Sciences“.

Special Issue Information

Dear Colleagues,

Electrochemical science is advancing rapidly, fuelled by breakthroughs in biological electron-transfer systems, next-generation catalytic materials, and increasingly sophisticated analytical methodologies. At the same time, the emergence of AI-enabled data analysis, autonomous experimentation, and machine-learning-assisted material discovery is reshaping how we understand, predict, and optimise electrochemical behaviour. These developments are accelerating progress across energy technologies, sensing, biomedical interfaces, environmental remediation, and sustainable chemical transformations.

This Special Issue aims to bring together contributions that reflect this evolution. We welcome studies that explore bioelectrochemical mechanisms, develop innovative electrocatalysts, characterise functional materials using advanced electrochemical or spectroelectrochemical techniques, or that integrate AI, automation, informatics, and data-driven tools into electrochemical research.

Scope and Themes:

  1. Bioelectrochemistry and biological interfaces:
  • Electron-transfer processes in enzymes, proteins, and biomolecular assemblies;
  • Electrode–biological interface engineering;
  • Enzymatic and microbial electrochemical systems;
  • Biosensors and wearable/implantable electrochemical devices;
  • Bioelectrocatalysis and bioenergy conversion.
  1. Electrocatalysis and catalytic material innovation:
  • Catalysts for ORR, OER, HER, CO₂RR, NRR, and related processes;
  • Nanostructured, hybrid, MXene-based, and MOF-based catalytic materials;
  • In situ/operando mechanistic studies;
  • Electrode degradation, kinetics, and interface stability;
  • Photo- and photoelectrocatalytic processes.
  1. Electrochemical analysis of functional materials:
  • Voltammetric, impedance, spectroelectrochemical, and scanning probe methods;
  • Electrochemical performance of energy materials (batteries, supercapacitors, and electrolyzers);
  • Charge-storage mechanisms and interfacial processes;
  • Functional polymers, ceramics, 2D materials, and composites;
  • Micro-/nanofluidic electrochemical systems.
  1. AI-enabled electrochemical and chemical analysis:
  • Machine learning models predicting electrochemical behaviour and catalytic performance;
  • Autonomous experiment platforms and robotic electrochemistry;
  • Data-centric electrochemical analysis: Datasets, pattern discovery, and algorithmic optimisation;
  • AI-assisted interpretation of voltammetry, spectroscopy, and impedance data;
  • Accelerated material discovery using generative and predictive AI.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 250 words) can be sent to the Editorial Office for assessment.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Applied Sciences is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2400 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
